After the application materials submitted by the applicant are rejected by the Industrial Bank Credit Card Center, the applicant may not continue to submit the application materials to the Industrial Bank, because repeated applications in a short time may be blacklisted by the Industrial Bank users after repeated rejections. It is suggested that the applicant call the Industrial Bank's credit card customer service number 9556 1, then switch to manual service, and then ask the staff about the specific reasons for rejection, and wait for more than three months after the last card application, and then continue to submit the application.
