无法通过交易商提款

我试图通过Wintersnow从我的账户中取款。但他们说我应该交税，并在他们设定的期限内再做 1 笔交易。我相信他们所说的，所以按照他们的要求纳税（如附件 1、2）并尝试按照他们所说的进行交易。但是什么也没发生。之后，他们再次要求更多的税款（如附件 3 所示），没有按照我的要求进行提款程序。有什么办法可以解决这种情况吗？

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?
