It may be overdue and the bank has frozen the card.

Freezing means that according to legal provisions, only law enforcement agencies such as the People's Court, People's Procuratorate, and Public Security Bureau can request banks to freeze accounts. The maximum freezing period is 6 months, and the freezing period will be automatically revoked after expiration. There is no unfreezing period at all. As soon as the freezing period required by the law enforcement agency expires or the bank receives the unfreezing notice, the bank will unfreeze immediately and it does not take any time. The only reason why the bank freezes the funds is that it has received legal documents from the court, procuratorate and other law enforcement agencies. The bank has no right to freeze the customer's account on its own. The second method is that the law enforcement agency that originally requested the freeze will submit the "Unfreezing Notice" stamped with the official seal of the law enforcement agency at or above the county level and signed by the person in charge, and the bank will immediately unfreeze it after receiving it.
