If I understand correctly, they refunded $100,000 that was the original bet and you received withdrew it to your wallet. After that they offered you $100,000 that you were told could not be withdrawn and had be used within Betfury as bets. According to your claim, they should have given you $300,000 as winnings and you should have been allowed to withdraw it all.

Having said that, I think Betfury should start paying attention to threads related to scam accusations against them otherwise they might find their reputation has suffered by neutral/negative tags and flags.
