How to structure a mobile and broadband complaint letter
Start with a concise summary of what happened, then set out the key dates, references and evidence. Keep the tone calm and factual. A business can respond more easily when the letter separates the problem, the impact and the outcome requested.
Telecoms complaints may involve a deadlock letter or ADR if the provider does not resolve the issue.
ClearComplaint uses this sector context to guide the letter structure, but you should always review and edit the final wording before sending it.
