How to solve the problem that the bank card is frozen if it is not accepted or paid?

I understand that when a bank card is frozen, you must first understand the reasons for freezing, and then provide supporting documents or evidence to unfreeze the account. Common reasons include abnormal account, arrears, suspected fraud, etc. In case of judicial freezing, the supporting documents issued by relevant units shall be provided; If the bank's risk control is frozen, it is necessary to provide proof of running water. Be patient and active during thawing, maintain good communication with the bank and actively cooperate with the bank's requirements.
