You can't. There are two reasons why you were blocked by the bank: first, your consumption was abnormal, and the bank suspected that you had cashed out illegally, so your card was blocked; Second, if you don't pay it back for a long time, the bank will freeze the card if it determines that it is risky. In both cases, the bank will ask you to pay off the money. In the first case, it is possible to unblock, but the amount will drop; In the second case, the bank will cancel the card after paying off.
