First, check if you have a sufficient balance in your Wallet at the time of the transaction with your payzy debit card. If the balance was insufficient, the change cannot be saved to your Piggy. If the current balance in your Wallet is now sufficient, then, on the next transaction with your payzy debit card, a new attempt will be made.
If the problem persists, you can open a support request using the yzy bot, in the ‘Help & support+F51’ section on your profile to help you.
