If the credit card is suddenly downgraded, you can try the following methods:

1. Call customer service to explain the situation and apply for unblocking the card.

2. Provide consumer invoices or POS machine receipts suspected of cashing out and submit them to the bank by fax scanning. And can be unsealed.

3. Re-apply for a card with different card types and apply for unsealing.

4. Foreign consumption.

5. Cross-regional restrictions are automatically unsealed.

Cardholders must keep the good habit of using the card and repay it in time, and the amount will increase rapidly.

cause

1, bad credit.

Some loan products with overdue credit information will also lead to poor personal credit information. If the credit information is frequently inquired by financial institutions in the past three months, it will also lead to changes in the credit information, which will affect the credit card limit and lead to a decrease in the credit card limit.

2. The card is not standardized

Illegal cashing, card maintenance and other bad card use behaviors have certain risks, and at the same time, they will reduce the quota and even get stuck.

3. The frequency of card use is low.

Credit cards that have not been used for a long time are no different from dormant cards, and there is also the risk of being downgraded. Banks also apply for credit cards in order to obtain corresponding benefits. If the cardholder does not use the card, the bank will think that there is no demand for using the card, so it will be downgraded.

4. The debt ratio is too high.

If the cardholder's debt ratio is too high, banks will generally consider the loan risk and reduce the credit card limit. After all, high debt will make banks question the repayment ability of cardholders.
