The most common reasons why credit cards are not accepted are as follows: First, the payment amount exceeds the limit set by yourself or the maximum overdraft limit set by the bank. In this case, it is only necessary to lower the payment limit or reset the limit. Second, the available amount is insufficient. In this case, you can only change the bank card to pay, or reduce the credit card limit. Third, credit cards are frozen. This situation is the most complicated. First, you should consult the bank to find out why your credit card is frozen, and then solve the problem before you can apply for unfreezing.
It is suggested that you should strictly abide by the bank's regulations when using credit cards.
