after the credit card is lost, you should report the loss immediately, and the account security can be guaranteed only after the loss is reported. There are many ways to report the loss: 1. Log in to the mobile banking client and operate through the menu of "Credit Card-Credit Card Report Loss". 2. Log in to online banking and operate through the menu of "Credit Card-Credit Card Management-Credit Card Loss Report". 3. Call the 24-hour service hotline of CCB Credit Card. After reporting the loss through mobile banking and online banking, the system will not reissue the card by default. If you still need to use it after reporting the loss, you should call the CCB customer service hotline as soon as possible to apply for a replacement card.

if you want to pay back, just pay back according to the card number.
