Unable to withdraw via Broker

I tried to withdraw money from my accounts via Wintersnow. But they said that I should pay some taxes and I should make 1 more trade even within period they set.
I trusted what they said, so transfered USD to pay taxes as they asked(As attached 1st,2nd) and tried to trade as they mentioned. But nothing happened.
After that, they asked more USD for taxes again(As attached 3rd) without Withdraw process as I asked.

Is there any way I can go forward to fix this situation?
