They change their story from "wrong odds" now to saying that I am a value bettor (which they concluded after just 1 bet!!!!), and therefore they have the right not only to limit my stakes but also confiscate all winnings.
You have given the reference of your bets from other sportsbook in the complaints. And BC.game have taken their decisions with the odds provider by giving the reference of your betting activity on the other sportsbook you have mentioned. It looks like they have used your trump card against you.
I will submit a complaint at Casino Guru too.
Unfortunately, Casino Guru doesn't take care of the sports betting related complaints.
