Before you start

1. The first place to start is with your retailer. In some cases, the retailer may have made a mistake and you can contact them directly to receive a refund or resolve.
2. In order to start the process of investigating the disputed transaction, you must have already contacted the retailer. Please fill in the relevant online form at the bottom of the page to give us details of the dispute. To make the process as straightforward as possible please follow these points:
   • if you are disputing more than one transaction and they are on different cards, please submit them on separate forms.
   • make sure the details you are putting into the online form are correct, as they will need to match our system. If you submit the form and they don’t match, we can’t process your case.
   • you may need some of the following documents to help complete the form: your bank statement, original order, return postage and receipts or invoices.
   • If it is an ATM dispute you will need the location information.
