Credit card interest is refundable.

First of all, call the bank customer service and request a refund of liquidated damages, but the premise is that you have paid off the debt and successfully applied to cancel the credit card;

The prerequisite for the bank to waive interest is, It is the cardholder who has a "strong" willingness to repay, but due to objective reasons, is unable to repay in full and on time!

Interest reduction can only be handled after the cardholder’s application, bank approval, and leadership review!
