From what I can tell, you are being accused of not paying people for prizes that they claimed to have won in contests run by you.
Im sure if you contacted each and every online casino out there, they will tell you they get accused of that every day.
What I think happened is that you came up with a clever idea to get people to sign up to some online casinos where you are an affiliate. You were counting on your affiliate earnings to cover the costs of the contests you were running. And when that didn’t happen..you ran into trouble.
Look..im not bashing you here. But there seems to be a lot of inconsistancies in your story.
By all mean…hire a lawyer. Maybe he can straighten out this mess for you.
