95568 Minsheng Bank texted me all day saying that I spent a lot of money ... I don't even have an account with this bank. What happened?

There are two possibilities: 1, Minsheng Bank makes a mistake, which is generally very unlikely;

Your current mobile phone number was left in Minsheng Bank when it was used by others before. He didn't cancel his mobile phone reservation after changing his number, so he sent you a text message.

You can call 95568 and ask them to stop sending it to you.
