Order recommendation caused losses?

My surname is Sun, operating some business outside my hometown. Unable to earn money in business, I began to seek other opportunities to make money.Recently,when making investment in stock,I received the information of platform from its online salesman,who was promoting his platform and the trader competition. Even doubting about it, I didn’t resist the temptation and deposited 350000 yuan to follow the so-called order-instructing teacher.While it was not the same as the salesman promised,with few profits,I made a heavy loss.I felt something abnormal,but consciously unwilling to doubt his teacher.As long as I made a loss,the salesman and teacher would boast with lots of nonsense and induced me to add fund to gain more profits than losses.I deposited more than 200000 RMB in total.After making a loss of 170000 yuan,my remaining 30000 was in the status of closed position.I wanted to make a withdrawal while it is unavailable.
