Is it true that Ant Group said it would go to the door to verify the information and hang up?

It's true. Your Alipay is overdue, and then Alipay will send you a text message saying that it will come to investigate. This is not a malicious collection for you. Maybe it's just a visit to find out your financial situation and see if you have the ability to repay. After all, Alipay is a formal payment platform. It has a business license, and it is not an illegal collection platform. It will not collect you violently and spread your information at will.
