Fake, Scam Broker

I had deposited $20,000usdt with Bohua Technology ltd broker. I did many Crypto trades and was able to withdraw a small amount. When I wanted to withdraw a larger amount, they rejected this, customer service banned me after complaining and my account was frozen.
I contacted Wintersnow limited broker via their website www.wintersnowfx.com and registered with them. I told them about Bohua technology Ltd and that they are no longer on MT5 platform. Wintersnow limited said that they would migrate my account from Bohua Technology Ltd broker and said that I will be able to deposit, trade via MT5 platform and withdraw.
I tried to withdraw $35,000usdt which was rejected. Then I tried to withdraw $25,000usdt which was also rejected, then I tried $35,000usdt again which was successful, debited from my account but never received and not credited back to my account.

I contacted customer service who said funds will be released if I paid 5% of my account balance to guarantee payment to my crypto wallet.

I believe that Bohua Technology ltd and Wintersnow limited are the same broker who allow people to deposit funds, trade but refuse to let people withdraw without some kind of extra payment.

please someone help me to recover my account balance and I am willing to pay someone 20% of my account balance if successful. Screenshots attached as proof
