Ok, no problem. We suggest you do the following (in this order):

  1. Contact your bank. It could be that they are experiencing issues from their end.
  2. Are you using an international card? If so, please try using a UAE card.
  3. Update your card details in the app.
  4. For more information on how to update your card details in the app, take a look at 'How do I change my credit card?'
