A strong telecom complaint defines the issues, the evidence and the remedy before the account disappears into generic customer-service correspondence.
Start by telling the provider that you are making a formal complaint and list each issue separately. Keep a dated complaint start point because access to ADR is now generally available after six weeks or sooner if the provider issues deadlock.
A complaint about billing, service, mis-selling and credit reporting may involve several frameworks. Do not let the provider answer one issue and treat the whole complaint as resolved.
Key points
- Use numbered complaint issues.
- Record the formal complaint date.
- Ask for a final/deadlock response if the provider cannot resolve it.
- Keep remedies tied to each issue: correction, refund, release from contract, credit-file amendment, compensation.
Define the scope
Write “My complaint has four issues” and list them. This creates a benchmark against which a final response or ADR decision can be audited.
Six-week ADR access
Since 8 April 2026, the general period before telecom consumers can take an unresolved complaint to an approved ADR scheme was reduced from eight weeks to six weeks. Deadlock can allow earlier referral.
Keep regulatory reporting separate
You can report conduct to Ofcom, but Ofcom does not normally resolve your individual dispute. Do not miss ADR deadlines while waiting for Ofcom.
In practice
- Confirm phone complaints by email or portal message.
- Keep screenshots of online complaint status.
- If the final response changes the provider’s factual story, identify the contradiction rather than rewriting the whole complaint.
What to do
A practical next-step plan
- State it is a formal complaint.
- List issues and desired remedies.
- Attach only the key evidence initially.
- Record each response and unresolved point.
- Request deadlock if appropriate or refer after six weeks.
- Present ADR with a chronology and issue schedule.
Common traps
Things that often confuse the issue
- Do not let repeated customer-service contacts obscure the formal complaint start date.
- Do not assume Ofcom will adjudicate compensation.
- Do not accept “final response” as proof every issue was answered.
Evidence worth keeping
A complaint remedy can have several components.
Depending on the facts, ask for correction of the account, refund/credit, removal of an invalid fee, correction of credit reporting, performance/cancellation, apology or reasonable compensation for evidenced inconvenience or loss. Explain why each requested remedy follows from a specific failure.
Useful wording.
“Please treat the numbered points below as the scope of my complaint and answer each separately. If you cannot resolve them, please issue deadlock and identify your Ofcom-approved ADR scheme.”
The ADR waiting period is now six weeks.
From 8 April 2026, eligible customers can generally use the provider’s Ofcom-approved ADR scheme after six weeks if the matter remains unresolved, or sooner after deadlock. Keep the original complaint date. If the provider gives a final position earlier, ask for deadlock rather than entering an unnecessary cycle of identical replies.
Ask for issue-by-issue answers.
| Complaint issue | Specific answer to request |
|---|---|
| Billing | Which term/event creates the charge and what adjustment will be made? |
| Service failure | What fault was found, when was it fixed, and what compensation/refund is due? |
| Mis-selling | What sales evidence was reviewed and how does it reconcile with the disputed representation? |
| Credit reporting | What data was reported, on what dates, and will it be corrected if the underlying balance is wrong? |
| Cancellation | What effective date and contractual termination charge calculation is being used? |
This makes it harder for a generic final response to close several distinct issues with one sentence.
Make sure your issue becomes a complaint rather than an endless support conversation.
State clearly that you are making a formal complaint and ask for the complaint reference and date. A telecom provider must have an accessible complaints code explaining how complaints are made, investigated and escalated. If an agent keeps treating a repeated problem as a fresh service ticket, write to the complaints channel and anchor the chronology to the original unresolved issue.
Complaint control
A support ticket and a complaint are not necessarily the same thing
Telecom providers often operate separate fault, billing and complaint workflows. A technical ticket may record that something is broken without recording dissatisfaction about how the provider has handled it. If you want the formal complaints process to start, say so clearly and keep proof of when the provider was put on notice of the complaint.
This matters because ADR eligibility can depend on the complaint timeline. For complaints within the current rules, unresolved telecom complaints can generally move to ADR after six weeks, or earlier if the provider issues deadlock. The Communications Ombudsman's current Terms also allow for cases where a consumer has encountered sustained difficulty registering a complaint.
Write the complaint as an issue list, not one long narrative
Telecom disputes snowball. A service fault can lead to support failures, a wrong diagnosis, a disputed charge, a failed callback, debt collection and then credit reporting. Number each issue separately so the provider cannot answer the easiest point and describe the whole complaint as resolved.
| Issue | Question to require an answer to |
|---|---|
| Underlying fault | What failed, when did it fail and what permanently fixed it? |
| Support handling | Were callback requests logged, and why were promised contacts missed? |
| Billing | Which contractual term or usage record creates the disputed charge? |
| Credit reporting | What data was reported, on what date, and what source records support it? |
| Remedy | What refund, correction, compensation or other action will be provided for each upheld issue? |
Callback promises are evidence: record the exact commitment
“Someone will call you” is weak evidence. “A technical adviser will call within 30 minutes” or “you will definitely receive a callback by close of business” is much stronger because the commitment is specific and testable. Record who made it, when, the promised time and whether it happened.
If a provider later says the callback was never logged, ask it to check the call recording, CRM notes, callback queue and escalation records. If it says the callback was logged but not completed, ask why. The objective is not to score points; it is to identify where the complaint process actually failed.
When the provider changes its explanation, make it reconcile the versions
Do not simply accuse the provider of “contradicting itself”. Put the two statements side by side. Identify the date, source and exact proposition in each. Then ask which statement is correct and what evidence supports the revised position. This is especially important where one version attributes the problem to the customer or contract and a later version admits an internal system or provisioning fault.
Useful wording
“Your response on [date] says [A]. Your later response on [date] says [B]. Those explanations cannot both describe the same event accurately. Please confirm which position you now rely on, the evidence for it, and what consequence the corrected position has for the remedy.”
Build an issue schedule before the final response arrives
Use one row per issue: allegation, key evidence, provider answer, remedy sought and status. When the final response arrives, mark each row answered, partly answered or unanswered. This is much more effective at ADR than arguing that the response “ignored everything”.
A changed explanation is evidence: not automatically proof of bad faith
Providers sometimes discover new facts during investigation. Record the sequence and ask why the position changed. The important question is whether the final explanation is supported by the underlying records and whether earlier incorrect advice caused a separate loss or delay.
