All casinos here are competing each other some of them may have some plans of destroying other's reputation or he could be telling the truth but it's hard to believe for just $880 that Betfury will ruin itself.
It's not even hard, but rather impossible for a site who would scammed their own user for $880 to ruin their name. I think the reason why no one representative from Betfury commented his comment because it's baseless comment. If he really got scammed or cheated, he just need to create an accusation about betfury, but we can see, nothing made by him.
