Send me a text message saying that I paid successfully with the WeChat payment function, but I didn't buy anything, and there was nothing in the WeChat bill. What happened?

First of all, let's see if you have automatic deduction, such as a small management fee of three yuan per month for bank cards. Then see if you have initiated home payment. Go and make sure your amount is small. If this is sent to you by WeChat, you can consult the official customer service of WeChat. Don't panic.
