GS fraud platform made me suffer losses

I was pulled into a group,in which there are teachers who gave order recommendation and showed screenshots of profits.Then they asked me to open an account to trade.I did so, When I lost money, I was incited to deposited money again to trade according to the market. I deposited money, but still kept losing. The advisers insisted us not to stop losses, asking me to add positions. The agent of the platform gave irregular order advice. After the losses, I was not allowed to withdraw money. He also told us to add positions, and then the account directly suffered a forced liquidation, making me lost all. Afterwards, I found that I was deceived. They just deliberately let us lose money. The money that I have earned so hard has been deceived.
