1. Banking system delay: Sometimes the banking system needs some time to process and update the repayment information. Usually, this delay is temporary. You only need to wait a moment or a few working days, and the system will be updated to successful repayment.
2. The transaction has not been processed: the bank may need to perform some additional verification or auditing steps to ensure the security and validity of the transaction. These audits may take some time, so during the processing, the repayment status may be displayed as "repayment in progress".
3. Insufficient bank card balance: If your bank card balance is insufficient to pay the credit card amount, the payment may fail or be temporarily suspended. Please make sure that your savings card or the account associated with the credit card has enough funds to complete the repayment.
If you are still confused or worried, I suggest you contact the customer service department of the bank directly to provide specific transaction and repayment details. They can provide you with accurate explanations and guidance to help you solve problems.
