God damned IX Securities! Losing money, position liquidated. Making money, unable to withdraw!

I’ve been doing business on IX Securities. I suffered two position liquidations, causing over 40000 RMB loss. I deposited more on IX Securities. Now I earned 65000 USD but they won’t let me withdraw and even skimped my profit. When I lost money, they didn’t give a damn. When I made money, they said I was tricking them. I lost contact with the service and the salesman even blocked me. They didn’t show me any related terms of service, just saying it is ok to lose money but I can’t withdraw when I earn. The former name of it is INFINOX, which they abandoned and started this brand. I believed it because they are information of it on FX110.com. Now the problem occurs. I hope FX110 could bring them to justice and give my money back. They salesman resigned to pass the buck. Their office in Futian, Shenzhen moved away. They won’t let me withdraw, giving me no response until now!
