first: call customer service, explain the situation and apply for unsealing. Credit cards will not be blocked for no reason, and banks will block cards for a reason. The most common is abnormal card sealing, which is also called stop payment. For example, your credit card transaction is abnormal, and you have day trading abroad. Then in order to prevent your credit card from being stolen, the bank will stop paying your credit card. At this time, you can take the initiative to call the credit card customer service, explain the situation, and emphasize that you have been spending only yourself, then you can unblock it.
second: according to the reasons for blocking the card, provide proof materials and apply for unblocking. This situation generally occurs when the bank suspects that the cardholder has cashed out. In order to prevent customers from continuing to cash out, it will cause losses to banks. It will directly seal the card. But at this time, if you can provide proof of your real consumption, such as receipts and invoices after consumption. Then the bank will unseal your credit card and let you continue to use it.
third: complain to the banking insurance regulatory bureau, explain the situation and ask the bank to unblock it. Again, in the above example, if you spend all your money, but you haven't kept the proof of consumption for a long time, but the bank has to let you provide it, otherwise it will be unsealed. Then at this time, you can complain to China Banking and Insurance Regulatory Commission, complaining that the bank has no reason to seal your credit card and terminate the contract without permission. After all, the bank can't come up with the evidence of your credit card cashing. If you just suspect it, you will seal your credit card, so you can complain at this time. At this time, the general bank will give the cardholder another chance to sign a letter of guarantee, and then the credit card can be unsealed.
fourth: after paying off the arrears, apply for unsealing. If your credit card is blocked due to overdue, as long as your overdue time is not long, you can apply to the bank for unblocking after paying off all the arrears. After unblocking, your credit card can still be used normally. However, if your overdue time is long, for example, it has been overdue for more than 3 months, then at this time, even after paying off the arrears, it is difficult to unblock it. Because it is overdue for more than three months in a row, it is maliciously overdue.
fifth: reapply for a second card. If your credit card is blocked, the bank will not unblock it for you. Then at this time, you can apply for a new credit card of the bank. If it passes, the amount will be the same as that of the blocked credit card. Then at this time, you can activate the new card, cancel the original blocked card, and use the new card. It is tantamount to unsealing in disguise.
