Huatongsilver scams!

I was invited into a group chat without notification in March. I was told the group chat was for us to share investment knowledge without charge. There was a teacher introducing stock . Then he taught us the investment technology in this group chat. Because I lost much in the stock market, I cared about the group messages. After few days, I began trusting him and usually asked him for advice. After a month, the teacher said the A-share stock market was unprofitable, we could invest with him in Huatongsilver. We could profit more! Later, he shared the profitable trade of his students in the group chat. I was attracted by the profit and joined Huatongsilver. After that, I opened an account with the help of an assistant. Once the teacher gave a recommendation, saying we can buy sell orders without stop loss and limit. I trusted him so I did as what he said. However, I lst all my account balance in the end. I deposited ￥500,000 in total. At that time, I realized that I was cheated!
