What is the hotline of public channel DV?

A micro-friend who has added WeChat for one year because of his urgent use of his mobile phone often posts screenshots of his mobile phone in his circle of friends. After chatting, he bought an assembly machine. As a result, WeChat didn't get blacked out, and friends didn't reply to the screen. The report on wechat is invalid. I have to announce the news. There is a transaction serial number, but there is no delivery. There must be many people who cheat money in this way and can't complain on WeChat! Legal China, for the people!
