Is GSDO safe?

First, I was invited into the group, where every day there are teachers giving order recommendations and showing screenshots of orders with profits. Then I was asked to open an account to trade together. I did. When I lost money, I was incited to deposited money again after their analysis if the market. I deposited money, but still kept losing. The advisers insisted us not to stop losses and not to stop out, asking me to add positions. The agent of the platform gave irregular order advice. After the losses, I was not allowed to withdrawing 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. I checked my bank statement, finding the money went directly to this platform, and did not flow into the market according to normal operations. Then I contacted the platform. When they learned that I wanted to complain about them, they immediately said that they had disqualified the agent and dismissed the account manager. I want to ask If they don't violate the rules, why do you do this? Also, the platform fully acknowledges the reverse advice, but they argue that it was resulted from the agent, and has nothing to do with their platform. I would like to ask: Is the agent of their platform not representative of the platform? Isn't the agency doing everything tacitly approved by the platform? Now that my money has all been lost, they shirked the responsibility immediately. How can you do that? Moreover, I was guided by an "adviser", who caused my losses. These are abnormal losses.
