Shopping in Guangzhou, meeting telecom to do activities. I spent 1299 yuan to buy Tianyi Card, Oulute M3 tablet computer and all-British S 10 mobile phone. Where should I report fraud?

I also met this scam at Fangcun Bus Terminal in May 1. When I got home, I thought more and more about the atmosphere. The next day, I went to Fangcun Bus Terminal to see if they were still there. Fortunately, I went at the right time when everyone was paying the bill. I said I wanted to return it. The person in charge was afraid that I would make trouble and ruined their good things, so he took me aside and asked me why I returned them. I said, "I don't want to say too much. I think you know yourselves very well. I don't want to prevent you from getting rich. Just give me a happy word, will you give it back to me? " I just paid back the money. It is really dangerous. I swiped my card for fear that someone would copy my card and password. I was afraid to think about it, so I went to the bank to change my password first.
