What to do if…
a card or merchant charges you more than once for the same purchase

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy UK guide

Short answer

Check whether both entries are completed payments rather than pending card authorisations. Save the transaction details, contact the merchant, and ask your card provider to dispute the extra payment if the merchant does not correct it.

Do not do these things

  • Do not pay for the purchase again while the entries are being checked.
  • Do not assume that every pending entry is a completed second payment.
  • Do not delete receipts, order confirmations, screenshots, statements, or messages.
  • Do not send anyone your PIN, password, full card details, or one-time security code.
  • Do not delay contacting your card provider if you do not recognise either payment.
  • Do not submit conflicting refund or dispute requests without keeping a record of each one.

What to do now

  1. Open your banking or card account and compare the entries. Record the merchant name, amount, date, status, and any transaction references.
  2. Check the receipt, order history, booking confirmation, or merchant account to confirm that you made only one purchase.
  3. Take screenshots or download a statement showing both entries. Keep evidence of the single order, including the receipt and confirmation emails.
  4. If either entry is marked pending, ask your card provider whether it is a temporary authorisation or a completed payment. A pending entry may change or disappear without becoming a second completed charge.
  5. Contact the merchant through contact details you have independently verified. Explain that one purchase appears to have been charged twice and ask the merchant to check its payment records and refund or reverse the duplicate.
  6. Keep a note of when you contacted the merchant, what you sent, who responded, and what they said they would do.
  7. If both entries have completed and the merchant does not correct the duplicate, contact your debit or credit card provider promptly. Ask it to investigate the duplicate and whether it can raise a chargeback under the relevant card scheme rules.
  8. Provide the card provider with the two transaction entries, the receipt or order confirmation, and your correspondence with the merchant.
  9. If you did not authorise one or both payments, report this to your card provider immediately using its app, official website, or the number on the back of your card.
  10. If the extra charge leaves you unable to pay for essentials or causes fees or interest, tell your card provider and the merchant when you contact them. Keep records of any resulting costs.

What can wait

You do not need to decide now whether to make a formal complaint or pursue further redress. First confirm the status of both entries, ask the merchant to correct the duplicate, contact your card provider if necessary, and preserve your records.

Important reassurance

Two similar entries do not always mean that the money has been taken twice permanently. Where a duplicate payment has completed, the merchant or card provider can check the transaction records, and chargeback may be available through your card provider.

Scope note

This guide covers the immediate steps for checking and challenging a possible duplicate card payment. A rejected dispute, continuing financial loss, or unresolved complaint may require further help from the card provider, the Financial Ombudsman Service, or another appropriate specialist.

Important note

This is general information, not financial or legal advice. Chargeback is not a statutory right and is governed by card scheme rules, so eligibility and procedures can vary. Contact your card provider promptly and follow its instructions.
