UnionPay is in front, spending 847 yuan. What's going on? Mine is postal savings card. The money spent was swiped by Qingdao Branch, and I have never been there.

I checked the postal currency card at noon and found that 600 yuan was missing. The bank said that UnionPay had two purchases in 300 yuan in advance. I must say this is for my own use. I don't know where the money went. I'll ask unionpay. UnionPay finally helped me find a consumer company. It's a business that Hangzhou's mobile phone number is recharged on Apple devices. People can spend it if they know the password, and they don't need SMS verification code. The Postal Savings Bank is not safe at all. How can I safely deposit money in such a bank?
