I want to complain to the HYCM platform, using activities to deceive users. There is a problem with the server, and the position is not closed for a week, which leads to my loss

I lost more than 71,000 US dollars on the HYCM platform, because they introduced me to the platform by tricking me into depositing money and giving gifts. As a result, there were no gifts, no bonuses, and the account manager was missing. They were very enthusiastic when they asked me to open an account on April 3rd. As a result, the account manager disappeared on July 20. It's a world of difference. In less than four months, I lost so much. It's all my hard-earned money all my life. I am already sixty years old, and I was cheated out of my life savings by a scammer. Later, I found the customer service on the official website of the platform and gave feedback on the relevant situation. The official website customer service not only did not solve the problem, but also forcibly closed the chat window. And they don't deal with my complaints. After I entered the HYCM platform, I traded a lot of orders. As a result, the position cannot be closed, resulting in a loss. They have various reasons to shirk responsibility. The relevant evidence is complete and cannot be uploaded in full. I hope that the relevant departments will strictly investigate and help me deal with it, thank you.
