Problem with a transaction

Firstly, don’t panic

In many cases transactions turn out to be genuine and people simply don't remember. We suggest a quick double check to make sure it's not something you actually know about and agreed to.

Is the transaction on your account?

Check your account online. If you don't have online access you can easily sign up to manage your account online.

Do you recognise the transaction or amount?

Check receipts, it's easy to confuse similar amounts. If you have additional cardholders on your account, check to see if they authorised the transaction.

Can you call the retailer / merchant?

Most retailers/merchants are happy to help if a mistake has been made. You may find their contact details on your receipt or the internet.

Raising a dispute

If you think there’s something wrong with a transaction you'll need to complete a disputes form so that we can look into it for you.

If your dispute is about a travel company that is no longer trading, this is the form you need

  • Remember to get in touch with the company that took the payment first, to see if they can help.
