Is ST safe?

STA woman named Cheng Lin added me into a stock exchange group(the world of shares). The advisers included Zhang Ruoyu, Shi Yin, Lao Wang, Lao Zhang in the voice stream studio. They recommended several stocks, but all are not optimistic. Later, they said that was because the stocks market was affected by the trade war and asked us not to invest in stocks. They let everyone trade A50 index for hedging, and let us deposit into ST. I deposited 25,000 US dollars in total. At first I gained a small profit. On the morning of May 30, the advisers let everyone to buy in short position with 70% of the positions. Because of the previous profits, I believe them. But all of my money almost lost in the end. The market raised up that day. On June 7th, the group was disbanded and I could no longer contact with them. Please punish these liars severely. Give my hard-earned money back.

They produced some “profit plans” things to boast themselves and keep asking us to deposit. Then they deliberately gave us wrong directions to make us lose.
