Gentlemen, I hate to say this but you're not likely to get either a response or your payment from this person.  It looked like a scam from day 1.  Next time don't join campaigns if there's no escrow or a reputable campaign manager.  It's just too damn easy to pull crap like this guy did, which is to get all the advertising he needs, all the profits from the project, and then not pay the campaign participants.  It's not hard to get an honest person like Yahoo62278 to manage a campaign, and if that isn't done you take the chance of getting scammed.

Oh, I'm aware of this.  It still looked scammy right from the start--and it was the lack of escrow that made it that way, and thus it isn't surprising that the end of it turned out like this.  You're just raging because of your feedback.  Can't help you with that.
