Once you have all of the documents we’ve asked for, you can submit a dispute request in the following ways:
- If the transaction is within your current statement period: log on to your Online banking, find the transaction you’re disputing and select ‘need help’.
- If the transaction is past your current statement period: call the phone number on the back of your Mastercard and an agent will help submit a dispute request.
When we receive your request, we’ll review the information and let you know if we will submit a dispute to the merchant on your behalf. We’ll let you know (by letter) if we submit a dispute to the merchant on your behalf.
