I currently have btc stuck in my 1xbit account which is now locked, so I am looking to withdraw it.

I deposited 25.4 mbtc in my account, and then placed a bet on a Nigerian football match, I was able to withdraw half of the money. But after that my account was closed. The bet won so there is still around 25MBTC in my account. Have talked to 1xbit security but they are being unresponsive, please help!!!???
