If you have an unexpected mobile phone charge, broadband contract dispute, disputed termination fee or recurring billing problem in Singapore, start by complaining to the telco or broadband provider in writing. Identify the service and bill period, say precisely which charge or contract term you dispute, and request an itemised explanation or correction. Keep a case number and the company’s response.
If the problem remains unresolved, Singapore’s IMDA Telecommunications and Subscription Television Alternative Dispute Resolution (ADR) Scheme may provide an affordable independent route through the Singapore Mediation Centre (SMC). It covers qualifying telecom and subscription television service disputes up to S$10,000 that occurred within the preceding year. Consumers generally pay S$10 for online mediation; the provider’s participation is mandatory once the consumer chooses an eligible ADR process. Read the official IMDA scheme and the SMC telecommunications page.
Quick action guide:
- Wrong mobile or fibre broadband bill: download the contract and bills, identify the exact disputed charge and contact the provider’s official support channel.
- Service outage or repeated disruption: report the issue to the provider and request a fault reference; note when the service was actually unavailable.
- Early termination or cancellation fee dispute: review the signed or accepted contract, start date, minimum term, notice period and any promotional conditions.
- Unsolicited premium service or added subscription: ask the provider to explain authorisation and billing and remove future charges where appropriate.
- No satisfactory response: check the IMDA/SMC ADR eligibility rules, including the S$10,000 cap and one-year period.
- Want an independent settlement discussion: eligible online mediation costs the consumer S$10, based on IMDA’s published fee table.
- Mediation does not settle the matter: consider the scheme’s separate determination option, noting the additional fees and binding nature of the decision.
- Bank credentials stolen or SIM-swapping suspected: secure the bank, telco and related accounts urgently; a routine billing complaint is not the only necessary action.

What Counts as a Telco or Broadband Complaint?
A consumer can be dissatisfied with connectivity, billing, plan changes, a mobile service, a fibre installation, a television package or the terms of a cancellation.
But not every dissatisfaction raises the same problem. Technical faults need troubleshooting and service recovery. Billing or contract disputes need a clear explanation of price, agreement and charges. Possible fraud may require urgent account-security and Police action.
The IMDA broadband consumer guidance advises customers to approach the internet service provider first about technical issues, billing or contracts. It identifies ADR as an additional route for contractual disputes rather than a replacement for initial troubleshooting.
To avoid confusion, this guide focuses on practical complaint preparation, escalating unresolved contractual disputes, and obtaining a fair explanation or remedy.
Step 1: Identify the Real Issue
Start with a short statement:
“My mobile bill for October 2026 includes an S$85 charge for a service I did not knowingly request. I would like confirmation of what the charge is, when and how it was authorised, and whether it can be reversed.”
This differs from: “My internet has been slow every evening since early October, and the provider has not resolved the reported fault.”
One issue concerns consent and billing; the other concerns service quality and technical support. You may eventually seek compensation or a fee waiver for the latter, but first establish what service was promised and what failed.
A detailed complaint should aim for a solution, not simply an accusation that the company is dishonest.
Step 2: Collect the Contract and Billing Evidence
Prepare:
- The account holder’s name and relevant account or service number.
- The provider’s legal name and service brand.
- The contract, order confirmation or plan terms.
- Promotional materials and any promised discount or installation offer.
- The bill or invoices showing disputed amounts.
- Payment records and previous statements for comparison.
- Customer-service chat transcripts, emails and SMS messages.
- Dates and reference numbers of earlier fault reports or complaints.
- Any written fee waiver, cancellation or plan change promise.
Keep information in chronological order. Use legitimate account access and secure file sharing, not public social-media posts containing the full account number or identification documents.
When there are several issues, split them into separate items. For example, S$30 incorrect roaming charge, S$20 late-payment fee allegedly caused by the error, and three days of broadband disruption may need different explanations.
How to Complain to the Provider
Use the telco’s official website, app, call centre, email or retail support route. Do not assume a person contacting you on an unsolicited social account is a genuine company officer.
A concise template is:
“I am disputing [charge/service/contract condition] on account [reference]. The relevant bill date is [date]. My understanding of the agreement is [specific point]. The evidence attached is [document]. Please explain the charge, investigate it, and confirm [refund, adjustment, service correction or another remedy] in writing. Please provide the complaint reference and expected next update.”
Keep a copy of the reply. If the provider offers a goodwill credit, ask whether accepting it resolves the whole dispute or only one issue.
Do not agree to a new long-term contract as the price of obtaining a correction without understanding the consequences.
Unauthorised Charges and Premium Services
Unexpected mobile bills may contain premium-rate content, subscriptions, roaming, excess data, international calls or value-added services.
The SMC telecommunications ADR description identifies billing disputes and unsolicited charges—including some premium and value-added services—as core examples of matters that may qualify for independent dispute resolution.
Before alleging wrongdoing, ask for the charge’s origin and authorisation evidence:
- What service was purchased or activated?
- On which date and using which device or account?
- What confirmation or consent does the provider hold?
- Is the charge recurring?
- How can future charges be stopped?
- What is the provider’s position on refunding the disputed amount?
A disputed charge may originate from a legitimate action, an error, unclear consent or possible misuse. The evidence determines the next step.
Broadband Outages and Slow Internet
A slow connection does not always mean the provider has breached a contract. Broadband performance can be influenced by the router, Wi-Fi interference, device hardware, home wiring, plan limitations and conditions outside the home.
IMDA’s broadband guide advises checking the home connection and approaching the service provider about performance.
For recurring outages, prepare a factual fault log: date, start time, end time, whether devices lost internet simultaneously, whether the router showed a fault and when the provider confirmed an outage.
What should you ask the provider?
Ask whether the fault is in the broadband line, provider network, supplied equipment or home setup. Request the diagnostic steps and whether a technician visit is necessary.
If the company promises a service restoration time, record that as a stated estimate rather than a guarantee. Later, compare the actual service experience with the company’s written promise and applicable contract.
Can you get a refund for an outage?
A refund or service credit may be possible depending on the provider’s contract, service commitments, facts and applicable scheme, but it is not automatically owed for every period of slow Wi-Fi.
Ask for a specific remedy and a written calculation. For an unresolved eligible contractual dispute, consider ADR after the provider has had an opportunity to respond.
For technical first steps, see How to Solve Problems in Singapore | Internet Down, Wi-Fi Not Working and Broadband Outages.
Early Termination Fees and Plan Cancellations
A telco may require a minimum subscription term, installation cost or promotional repayment if a customer cancels early. But the applicable amount should be based on the actual agreement, not simply stated without explanation.
Check:
- Contract date and minimum service period.
- Whether the plan included a device, router or installation subsidy.
- Any written fee-waiver promise.
- Whether you gave the required notice.
- The date the provider accepted cancellation.
- Whether billing continued after the effective termination date.
- Whether a move to another address changed the service terms.
If you dispute a charge, ask the provider to identify the clause, fee calculation and effective date in writing.
What if the company says the plan renewed automatically?
Review the renewal notification and terms applicable to your product. Ask when the new contractual period began and what customer consent or notice is relied on.
A renewal provision may be valid, invalid or subject to specific requirements depending on the circumstances. Do not accept an unsupported statement that all automatic renewals are unlawful or that they are always enforceable.
What Is the IMDA ADR Scheme?
The Infocomm Media Development Authority (IMDA) established a consumer ADR framework, administered by the Singapore Mediation Centre (SMC), for qualifying telecommunications and subscription television disputes.
The IMDA ADR scheme page describes an extra avenue alongside CASE and the Small Claims Tribunals.
Its design is consumer-oriented: once a qualified consumer elects to use the process, the service provider must participate under the scheme’s legal arrangements.
The process does not guarantee that the consumer wins or obtains the full amount requested. It provides a structured route for considering both parties’ evidence and attempting a fair resolution.
Who Can Use ADR?
The scheme covers eligible individuals and small businesses with qualifying telecom or subscription television contractual disputes.
Important conditions include:
- The dispute value is no more than S$10,000.
- The issue occurred within the past one year.
- The matter relates to a covered telecom or subscription television service.
- The dispute may be remedied through service recovery, in-kind compensation or monetary compensation.
- The customer has already approached the provider about the matter.
- The dispute does not fall under one of the published exclusions.
The one-year period is not the same as the Small Claims Tribunals’ general two-year rule. Confirm your actual dates before paying an ADR fee.
What Types of Disputes May Be Covered?
The SMC service description lists representative disputes involving:
- Mobile calls, data and SMS charges.
- Unauthorised or unsolicited value-added and premium-rate charges.
- Fibre broadband and connection services.
- Billing adjustments, waived fees and refunds.
- Subscription television services.
- Contract or service recovery issues within scheme scope.
The precise outcome can depend on whether the issue concerns a licensed service provider’s covered service and falls within the financial and time limits.
A provider may be required to participate in ADR, but that does not mean every product sold through a telco invoice is included.
What Is Not Covered?
The IMDA exclusion list includes:
- Over-the-top streaming services, such as certain unrelated video or music streaming subscriptions.
- Ordinary app store purchases billed on behalf of third parties, subject to specific exceptions for premium-rate services.
- Payphone and directory services.
- Matters that are criminal offences or public-agency regulatory investigations.
- Disputes already determined by a court or certain tribunals.
- Disputes that are currently before a court or other ADR body.
- Issues involving third-party equipment not within the specified provider responsibility.
- Claims for lost business revenue or profits caused by a service outage.
- Some complaints about customer-service performance alone.
- Legal expenses.
Read the exact exclusions before filing. A dispute may be emotionally frustrating yet still fall outside the scheme.
Can a Netflix or app store subscription be handled under this scheme?
Not necessarily. The scheme distinguishes the licensed telecom service from unrelated OTT streaming and third-party app-store billing. Use the relevant app, payment provider, CASE or other appropriate consumer channel.
How Much Does Telecom ADR Cost?
IMDA’s published fee table states the following consumer shares:
- Online mediation: S$10 to the consumer (the provider pays the remaining S$90 of the S$100 fee).
- Determination after mediation: S$225 to the consumer.
- Direct determination without mediation: S$375 to the consumer.
These are distinct procedure stages. Determination is not automatically free after paying the S$10 mediation fee. A consumer should understand the total relevant cost and consequences before choosing to proceed.
The published amounts and procedures may change; check SMC’s current payment instructions before submitting.
Mediation Versus Determination
Mediation is an opportunity for the parties to reach an agreed settlement with the help of an independent neutral person. The mediator does not simply impose the consumer’s requested outcome.
Determination involves an appointed decision-maker assessing the submitted evidence and reaching a decision. IMDA states that a determination under the scheme is final and binding on both customer and provider.
This is a major choice. A binding decision should not be requested casually without understanding the evidence, likely fees and consequences.
A reasonable consumer may choose to begin with the lower-cost mediation process and consider other options if no agreement is reached.
How to Apply Through Singapore Mediation Centre
Use the IMDA ADR information page to open the correct application pathway administered by SMC.
The broad sequence is:
- Contact the telco or broadband provider first.
- Preserve its response and complaint reference number.
- Confirm that the dispute is within one year and not over S$10,000.
- Check whether the product and problem are covered by ADR.
- Prepare the account information, contract, disputed bill, communications and evidence.
- Submit the appropriate ADR request through the SMC portal.
- Pay any relevant applicant fee under the published schedule.
- Follow mediation or determination instructions, providing accurate documents and a clear requested resolution.
SMC provides information about the service at mediation.com.sg/service/telecommunications. For scheme enquiries, IMDA also lists odr@mediation.com.sg and +65 6252 4226.
What if I am uncomfortable using the online system?
IMDA says eligible customers who cannot reasonably use digital channels may request in-person mediation or a document-based determination through the ADR operator, subject to its conditions and available appointments.
Ask SMC what accessibility, language or procedural assistance is available.
What Evidence Makes a Strong ADR Submission?
A good submission avoids repeating the same allegation many times. State:
- The contracted service and provider.
- The relevant dates.
- What was promised and how.
- What actually happened.
- The financial amount or service remedy being sought.
- What the provider said when you complained.
- Why you disagree with that response.
- The documents supporting your position.
For example, you may dispute a specific S$120 roaming charge, provide the plan’s roaming limit, list the travel dates and attach the provider’s explanation.
That is more useful than claiming the whole company is dishonest without showing how the amount arose.
What if the Disputed Amount Is Small?
A minor disputed charge might be resolved directly by the provider once someone reviews the account carefully.
Before paying for ADR, ask for an itemised bill, investigate whether a legitimate promotion ended and confirm whether a requested refund or credit has been granted.
For a dispute of S$15, a S$10 mediation fee is a significant fraction of the amount. A formal case may still be warranted for principle or continuing harm, but the consumer should weigh the real cost and benefit.
Avoid letting a small charge grow through multiple unreviewed recurring bills.
What if the Bill Is So High You Cannot Pay?
Explain the financial position to the provider promptly, without conceding the accuracy of disputed items. Ask how the company handles an outstanding balance while it reviews the complaint.
Do not assume that sending a complaint automatically pauses collections, late fees or suspension. Check the contract and ask for written confirmation of any temporary arrangement.
If your household cannot afford basic necessities, seek appropriate social support in parallel. See Getting Help in Singapore | Financial Assistance and ComCare Applications.
A billing dispute is not automatically a government grant or waiver programme.
What if an Unauthorised SIM Swap or Account Takeover Is Suspected?
A suspicious SIM change, account takeover or banking compromise is primarily a security matter, not merely a dispute about a monthly service fee.
Contact the telco’s verified fraud or security support immediately. If banking apps or transactions may be affected, contact the bank without delay.
Check whether the account has been modified or whether new devices or plans have been added without permission. Secure other linked accounts and preserve relevant evidence.

CASE and Small Claims: Other Routes
The Consumers Association of Singapore (CASE) handles appropriate consumer-to-business disputes and may offer negotiation or mediation assistance with applicable fees.
The Small Claims Tribunals may handle certain qualifying contractual disputes, subject to their own jurisdiction, limits, deadlines and filing procedure.
However, IMDA’s ADR scheme has specific exclusions for matters already before courts or other ADR bodies. Avoid starting several formal proceedings simultaneously without understanding the consequences.
See Getting Help in Singapore | Consumer Complaints, Refunds, CASE and Small Claims for the difference between these routes.
Four-Week Practical Complaint Plan
Day 1: confirm the disputed bill, protect account access and contact the provider through a verified channel. Ask for a case number.
Week 1: collect the relevant contract and evidence, receive a billing or technical explanation, and request a specific remedy.
Week 2: follow up on promised action. If the provider has not resolved an eligible contractual matter, review IMDA’s ADR criteria and costs.
Week 3: prepare or submit the SMC application when appropriate. Keep the dispute amount and claim dates accurate.
Week 4: follow the agreed mediation or determination process and preserve any final agreement or decision.
This is a reader’s planning example, not an official scheme timetable. An expiring one-year eligibility period or urgent account-security threat requires prompt action.
Frequently Asked Questions

The Next Useful Action
Write one precise complaint to your telco or broadband provider and request a documented response. If the contractual matter remains unresolved, compare it with the S$10,000, one-year IMDA ADR criteria and ask SMC about the appropriate application and costs.
The goal is not endless customer-service calls. It is a clear account of what was contracted, what went wrong and a proportionate, independent route to a fair resolution.
