Post your complaint here on their
main thread so they could answer. Did you place your email address when they asked, after you send your bitcoins to a specific address? If yes then you should receive an email from them. I see your bet listed on this
page everyone is using an account wallet except you which used a btc address.
Payouts aren't always instant there you might have to wait an hour or two before they send back your money. That's how my experience goes with receiving my winning bet with them.
