Are you asking what to do if the CITIC Bank credit card repayment shows that there is no second-class card account? The solution to this situation is as follows:

1. Open a second-category card account: If you have not opened a second-category card account, you can go to the CITIC Bank counter or online banking to open one. After activation, you can link the second-category card account to the credit card account.

2. Link the second-category card account: If you have opened a second-category card account, but you cannot select the account when repaying the credit card, it is because you have not linked the second-category card account to the credit card account. You can go to CITIC Bank online banking or mobile banking to perform related operations.

3. Contact customer service: If none of the above methods can solve the problem, it is recommended to contact CITIC Bank customer service for consultation and resolution. Customer service staff will provide you with appropriate help and guidance based on specific circumstances.
