That's what the contract says, right? I also use CCB's credit card. It is clearly stated in the credit card charter of CCB that all cash advance transactions that are not fully repaid or repaid on time are not entitled to interest-free treatment. It's no use going to court. The bank didn't violate the rules. As for its overlord clause, all banks are like this. If your credit card is opened, it means that you have approved the relevant provisions of the bank credit card regulations. You can choose to pay in full, right? There is no cost, and you also enjoy an interest-free period.

If you can't repay in full, you can apply to the bank for installment repayment, so the handling fee will be half lower than the interest you generate according to the minimum repayment amount. Of course, some consumption cannot be repaid in installments according to bank regulations.
