1. Cannot apply for cash installment suddenly. If there is something wrong with your credit card, the bank will not immediately reduce your credit limit or seal your credit card. Most banks will close some credit card business first to remind you to use your card reasonably, such as disqualifying you from cash installment. If you find that your credit card can't handle cash installment suddenly, the system prompts that "cash installment is only open to high-quality customers, and you are not eligible to use cash installment at present". Be careful when this happens, because you are likely to enter the bank's risk control list.

2. Received the risk warning notice from the bank. Generally speaking, if you receive a short message from the bank or a phone call from the bank to remind you of the risks in recent credit card transactions, please standardize the use of cards and the like. Then you should pay attention. Receiving this information means that your credit card has been controlled by the bank. The bank's risk control system automatically grabs your account. In short, you must pay attention to swiping your card, otherwise your credit card will be blocked easily.

3. directly reduce the amount or seal the card. For such a bank, the most representative is Bank of Communications, which may directly reduce the amount or even seal the card without warning. Credit cards with large traffic lines are the easiest to be blocked. I believe that there are not a few card friends in China Merchants!

Cancellation is actually very simple. You can get a credit card risk report from the card review, which will provide your credit card consumption behavior analysis and credit card transaction behavior analysis, find out the reasons, and then take the initiative to explain to the bank that your credit card is normal consumption, and provide invoices, receipts and other consumption vouchers. As long as you tell the bank that you are a real transaction, the bank will naturally help you cancel the risk control.
