Huaxia credit card audit is not always a return visit. The Credit Card Audit Department of the Bank will conduct audit through various channels and ways. Telephone verification is just one of them, not a necessary process. There will also be cases where the audit results will appear without a telephone call back, and the applicant needs to wait. If the audit department needs to confirm the information, it will also send a text message to the applicant, and the applicant can also contact the bank by phone to consult the audit progress.
