Disputed transaction Fraud / unauthorised payments Chargeback / refund dispute Section 75 claim Interest / fees dispute

How it works

1) Add facts What happened, key dates, and who you spoke to.
2) Pick an outcome Refund / replacement / compensation / correction.
3) Send with confidence Clear structure, calm tone, next steps.

Tip: receipts, screenshots, order numbers, account references, and chat/call notes help — but you can still complain effectively without them.

Escalation and evidence

If you do not get a satisfactory response, you can escalate. The right route depends on the sector and whether the firm uses an ADR/ombudsman scheme.

  • Sector: credit-cards
  • Regulator / ombudsman / ADR: Financial Ombudsman Service (FOS) (after the firm’s final response, or if 8 weeks pass without a final response).
  • Typical wait before escalation: Allow up to 8 weeks for a final response. If you receive a final response you disagree with (or 8 weeks pass without one), you can escalate to the Financial Ombudsman Service (FOS).
  • Evidence that helps: Statements, transaction details (merchant, date, amount), screenshots, order confirmations, delivery/tracking, chat/email logs, complaint reference, and any chargeback/Section 75 correspondence

Your letter should request a written response and set a reasonable deadline.
