After the loan expires, the bank will contact you for a period of time and send someone to negotiate with you. If the money cannot be exchanged, the bank will initiate legal measures.
If you don't pay it back for more than three months or the bank makes two reminders, you are suspected of credit card fraud and malicious overdraft, and the bank will sue you.
Malicious overdraft refers to the behavior that the cardholder overdraws beyond the prescribed limit or time limit for the purpose of illegal possession, and refuses to return it after being urged by the issuing bank.
