Failure to answer the credit card return call will affect the credit card approval.\x0d\The credit card return call is the most direct way to verify whether the applicant is applying for a credit card in person.\x0d\It doesn’t matter if you don’t receive the call the first time. After seeing the phone call, call back within the business hours of the card department. If the return call is not answered multiple times, the card department will reject the credit card application because "the verification phone number has been dialed multiple times and no one answered, so verification cannot be done."\x0d\ It is recommended when applying for a credit card , regardless of the applicant's mobile phone or landline, the applicant must leave his or her frequently used mobile phone number or have someone answer the landline, so as not to affect the credit card verification and approval.
