Ponzi Scam + bad attitudes toward customers

I withdrawn 405USD from my account, it passed two months and I still haven’t received my money. At first, I politely asked the customer service and the person in charge for about 10 times to fasten the withdrawal time, they replied me with their typical customer service script with no action taken. The person in charge said if I wish to fasten my withdrawn process, I must introduce new customer into USGFX, this is a Ponzi scam, the whole USGFX is a scam. they cheated my 405USD
