If the user's credit card is frozen but needs to repay, the user can choose to go to the counter of the card-issuing bank for repayment. After the credit card is frozen, the user can apply for unfreezing. If it is frozen due to overdue payment, then after you have completed the repayment, you can call customer service to declare that you have repaid and applied for unfreezing. In this case, the success rate of thawing will be higher.
