I may have an idea that will help you. This technique has worked for a friend of mine that purchased a piece of production machinery (brand new) which was built incorrectly and was never going to function correctly for the intended purpose. What was done was to have a half dozen t shirts printed advising the readers of the t shirts to not deal with the manufacturer/ seller and to ask the wearer for the info. These six shirts on six friends were worn at the once yearly national trade show for this industry. The offending parties immediately returned the money and had the machinery shipped back. You may want to check with a lawyer first. Sorry to hear you are going through this, makes one think twice about buying a Lamborghini doesn't it.
