Universal Internet Advertising Scammed me out of $12,000.00 U.S to advertise a website that makes no money at all! Tempe, Arizona

Universal Internet Advertising in Tempe Arizona talked me into setting up a website to sell products for amazon.com. They charged me $12,000.00 for advertising with the promise of a full refund if I changed my mind.I realised I would have to sell about $400,000.00 worth of products just to get my $12,000.00 back!I phoned them within 4 business hours to ask for a refund but they refused even though the writen agreement clearly states that they offer a 14 day full refund on products /services .Everthing they told me about the website and its money making potential were lies! It is all a great big scam!
