Contest Holder not paying

I wasn't really sure where to post this. I recently entered a contest and was told the contest holder was buying my banners. I did not watermark them and now it seems the contest holder (mymindrules) has no intention of paying. He declared a winner (seotraining) who hasn't been online since early February so this is smelling like a scam. Any suggestions what I can do? Can I make a complaint against 'mymindrules'. Any help appreciated. Thanx
