Sorry to say but "admin" cannot help you with this matter. This is out of their jobs in this forum. You can only settle this issue between you and 1win. Though it might be tough since the OP has been inactive, let's still wait for them to reply to you. Expect the worst since some users here provided some of 1win player's comment that they cannot also withdraw their funds out of the casino.
If they really scammed you, I agree to you, you should open a scam accusation for them, it will help the community, and maybe you too.
