First, you need to make sure that all the steps have been done correctly and that the process has been completed successfully. Then you can check whether your card has been charged.
If you find that your card has not been charged, you can contact your bank to find out why the transaction was not completed.
If your card has been charged, but the money has not yet shown up in payzy, then you will need to open a support request in the yzy bot from the "Help & Support" section and report the case, along with the time of the transaction, the card number in the format 1234 56** **** 7890 (first 6 and last 4 digits) and the amount.
You will be notified via the app of the outcome and any actions you may need to take.
