If it is a China Merchants Bank credit card, there are generally two situations when the card is frozen due to overdue payment: 1. After the repayment is received, the card limit is restored immediately; 2. The card cannot be restored after the repayment, and you can directly cut the card You just need to handle it properly afterwards. There is no need to log out, and it cannot be logged out. Generally, if it is overdue for more than 30 days, it may be the second situation, and the application will not be approved. If you want to check which situation your card belongs to, you can call China Merchants Bank customer service to inquire.
