1. Maybe the account number is abnormal. After the account status is restored, the limit will be restored naturally.

2. If it is overdue, you need to take the initiative to contact the bank to apply for restoring the line after paying off the arrears.

3. If the bank is suspected of cashing out, it can take the initiative to explain the situation to the bank and apply for the amount of recovery.
