What is the free delivery of lightning treasure POS machine for?

I feel that all their lightning products are deceptive. A few years ago, Guangzhou Lian Fang Investment Consulting Co., Ltd. sold me lightning products, bound my credit card and deducted my deposit of 65,438+028 yuan. Now I want to untie their devices, cancel their accounts, and ask for a refund of the previous deposit, but their app has been removed from the app store, and the entrance on the official WeChat account is also a risk warning that their products are unsafe. I called the staff of the company to answer the phone, saying that my machine was set up a few years ago and asked me to go to the salesman at that time. No matter what their company does, their words are full of irony! It's really clear that it cheats users, cheats users. This company is obviously a cheating company and is suspected of fraud. I said I would report it if I didn't handle it, and I said I would report it if I wanted to. There is really no king's law in the world! ! The key 128 yuan is not much, but I don't know how many people have participated in this routine. This company does earn black money, but it called 123 15 to complain that it can only take legal channels, but who wants to sue for this money! I don't know where to report this payment tool!
