First, check whether your repayment has been deducted successfully. You can check your bank card or online banking account to confirm whether the repayment has been deducted successfully.

If the repayment has been successfully deducted, it may be caused by the failure of the banking system. In this case, I suggest you contact the customer service of CCB to ask why the repayment has not been recorded and ask the bank to solve the problem as soon as possible.

If the repayment is not successful, it may be because your bank card balance is insufficient or your bank card has reported the loss. In this case, it is recommended that you make up the balance in time or replace the bank card to repay again.
