CITIC Bank's credit card is a big risk control company. There are several things to do to increase the quota: 1. Good credit reporting means that all credit products should be repaid in full and on time. 2. Use the card well, have real consumption, swipe the card many times, and don't always set the card blank. 3. Appropriate staging, let the bank improve your trust! Do you think you can call to apply for a refund after three months?
