Usually, if there is too much credit card debt, the cardholder fails to repay it in time, or the cardholder applies for reporting the loss of the credit card, the bank will freeze the cardholder's credit card account in this case.

When a credit card expires, the bank will generally issue a new card one month ago and keep the old card. The mailing address of the new card is the paper billing address. If you change your address, remember to contact the issuing bank in time to modify it.
