Cheated by an agent. Forced liquidation wthin one week. Can't withdraw

I knew a guy on the net and met him. He asked me to invest in USGFX but my account was wiped out within one week. There was a little money lefet, and he said he would help me earn my principal back. The nhe combined my accounts together to scalp orders, no profit. Now, I can't witdhraw. I just know he is an agent of USGFX
