The system asks authorization from your bank as a common bank practice. In some cases, a bank refuses the payment when you pay using a card.
This can have multiple reasons, however, the bank does not inform us about the exact reason to respect your privacy. We are unable to give you specific information but to resolve this, all you need to do is to contact your bank for any details and the status of your account.
Sometimes. it is also blocked due to our fraud filters for your account security. If your bank tells you everything is okay from their side, please submit a request with your details and we'll look into your payment status as soon as possible.
