1, call customer service to ask about the situation: first, call customer service to ask in detail what caused it. If it is because of overdue cashing, then this is the punishment for your illegal operation. If the bank thinks your credit card is risky, you can ask the bank to reissue it for you.

2. When using a credit card, always remember to repay on time, because the bank will charge a high late fee and interest for overdue repayment. It will also affect our credit history. Moreover, when the cardholder is overdue for many times or reaches a certain overdue amount, the bank thinks that the cardholder has malicious overdraft behavior and will lower the limit or seal the card.

The bank will have a special system to manage the issued credit cards. When the bank thinks that the credit card has been swiped on a risky POS machine, or the system prompts that the credit card has been hacked, for security reasons, it will stop paying the credit card.
