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.

Chargeback and Section 75 (where relevant)

Chargeback is a card-scheme process that may allow a payment to be reversed in certain circumstances.
Section 75 is a legal protection for certain credit card purchases. If you believe it applies, say so and explain the breach/misrepresentation and the remedy you want.

American Express (UK) complaints FAQ

How long should I give American Express (UK) to respond?

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 may be able to escalate to the Financial Ombudsman Service (FOS).

What evidence should I include?

Include transaction details (merchant, date, amount), statements, screenshots, order confirmations, delivery/tracking, and copies of chats/emails. Add your complaint reference and any prior decisions.

What if my dispute or claim was rejected?

Ask for the reason in writing, address it directly with evidence, and request a reconsideration. If you still disagree after a final response (or no final response in time), you may be able to escalate to FOS.

Is Section 75 the same as chargeback?

No. Chargeback is a card-scheme process. Section 75 is a legal protection for certain credit card purchases. Your letter can ask the issuer to confirm which route applies and explain their decision.

Should I contact the merchant first?

Often it helps to contact the merchant first, but you can complain to your card issuer about unauthorised payments and about how a dispute, chargeback, or Section 75 claim was handled.
