USGFX’s trader operated my account and made my position liquidated within two weeks.

I opened an account on USGFX under the introduction of USGFX’s people and deposited $5000. He said he can help me operate my account and double my balance in a month. However, my position was liquidated within two weeks. I questioned him but he said I need to shoulder my own risk he blocked me. I called USGFX phone in Australia but no one answered. This is a scam.
