How do I delete a payment method?
If you wish to delete a credit card, you can go to the ‘account’ option in the left-hand column of the admin panel and then ‘payment’. Here, you can tick the box beside the credit card information and press ‘delete’.
If you wish to update the credit card on your account, for safety reasons you cannot amend the details. You must delete the old card and enter the new card details via the ‘add credit card’ button.
