The Credit Card Center will not intercept your address book. Because it is illegal to pressure borrowers to repay by intercepting their address books and is not allowed by law. In addition, when applying for a credit card, generally only two contact persons are filled in, and the contact persons are filled in by the applicant. Even if an overdue behavior occurs, the bank will only contact the two people filled in by the applicant. As long as the relative numbers are missing from the address book, it may be that there is a malfunction in the mobile phone system. You can forcefully shut down the phone, reopen it, and search the address book again. However, it may be because the grouping is set, and the relative group is not found when searching. So there is no relative number.
