An “underpayment” occurs when you have paid less than the amount we expected. As a result, the payment will be returned to you.
You can claim your fund following the instructions in the email.
We cannot send the refund amount directly back to the wallet address since the address often does not represent the customer’s specific address. Therefore please reply with a refund address.
To Complete the Payment
Proceed with the transaction with your merchant by sending the exact amount before the payment expiry time.
