I tried to contact Yas.bet here on bitcointalk but he doesn't receive messages from newbies...
User 'YASBET' has not chosen to allow messages from newbies. You should post in their relevant thread to remind them to enable this setting.
I sent a message on your behalf directing him to this thread he has not logged in for the last three days maybe because of the holiday season, if he logs ins and there's no response you can proceed to create a flag, and we'll support the flag to alert the gambling community, hope you still get a positive response and recover your funds.
