We suggest that you first check your online banking account. There may be an option such as “Card History” or “Debit Cards” showing your previous card details. We require a screenshot of the card history, which must also include your name and card number.
Failing that, you can call into a branch of your bank where they will be able to print out proof for you. This document needs to be signed/stamped by you bank to certify its authenticity.
