Hello, I would like to ask why I can't add the CCB bank card for mortgage repayment. When repaying the mortgage, I encountered the problem that the CCB bank card could not be added. There are several reasons for this:

1. Bank card information error: Please confirm whether the bank card number, cardholder's name, expiration date, CVN and other information you entered are correct. Entering the wrong information will cause the addition to fail.

2. Abnormal bank card status: Your bank card status is abnormal, such as overdue, loss reporting, freezing, etc. , it will also cause the addition to fail.

3. Network or system problems: Sometimes the network or system of the bank fails, which leads to the failure of adding bank cards.

4. Bank restrictions: Some banks will restrict the addition of bank cards at a specific time or place, and the addition cannot be successful beyond the limit.
