I opened an account at BT Markets, ID: 311574. I made a withdrawal order of $1,348 but the floor did not approve it. Calling the hotline, they only receive and notify the relevant department to process, then a staff member calls (0598400623) to report. is a support staff of the exchange (named Tien Thanh), informed me that I need to confirm the owner's account = and how to buy a stock code, then the exchange will process the withdrawal order, the first time I did not buy, and after a waiting period According to the exchange's regulations, it is 48 hours, but the exchange still does not process my withdrawal order. I contacted the signal support specialist in the Group (when I entered the exchange, I contacted this specialist to deposit money and transactions) to ask for assistance in checking my account, he said he had already reported it to the police department, and my account was suspected to be an intermediary account and buying stocks to verify the owner's account was of course necessary. , then when the support staff of the exchange called back to confirm the owner's account, I followed the request and bought COTTON shares. When I just bought 1 COTTON share, my account status changed to NEGATIVE $6,999. At that time, the support staff also hung up. I called immediately but did not answer the phone. I reported the incident via the exchange's hotline, but it was just receiving and transferring information, without a specific time for me to process it. The following days I called the hotline again and received the same answer as before, "waiting for the relevant department to handle it". I texted the support specialist and the signal support staff (Khanh An) informing me that I was scammed, but they said no one was scamming anyone (I didn't get scammed, so I don't have to write these lines). and I was also removed from the signal-receiving group. I have proof of the call from the support staff (Tien Thanh) instructing me to buy COTTON shares and related evidence.
