The possible reasons for the failure of credit card repayment are as follows:

1. Please verify whether the card number and name entered are correct. It may be because the card number and name entered are incorrect or inconsistent. The bank was unable to verify the correct information, so the repayment could not be made.

2. It may be caused by temporary system failure (the probability of occurrence is very small).

3. After excluding the above reasons, the repayment transaction may be affected by the system and bank settlement (the probability of occurrence is very small, usually after 23:00 at night and before 4:00 in the morning).

4. Please verify whether the number of repayments has exceeded the limit: the number of repayments on a single credit card on the Yipay client cannot exceed five times in a single day, and the number of repayments on each Yipay account in a single day cannot exceed 10 times. If the number of times has exceeded the limit, it is recommended that you switch to another Yi payment account for repayment.

If the above reasons have been eliminated and the repayment still fails, you can call the Yipay customer service number and press 0 to transfer to manual or contact the online manual service for verification.
