Fill in the unit to prove that you have a fixed job and income. If you maliciously pay late, the bank will call your company to recover and leave the phone number of your colleague or friend. First, confirm your identity. Malicious overdue payment can't find you, so you can contact them! After receiving the receipt, the bank will ask your company or address, the company's fixed telephone number, and your relevant personal information (the content filled in when applying). Without a fixed telephone, it is difficult to solve this problem. You can consult the service personnel who help you with your credit card.
