I think you have definitely been scammed. First of all, I would write down any specifics that you can remember - the guys name who you spoke with, etc. If its a big company, you should try to get in touch with someone at the corporate level.
Also, I know consumers who have problems like that can go to the Better Business Bureau. I had a problem with false advertising and a health club and my boyfriend said the BBB helps consumers with stuff like that. I dont know much about it, but worth looking into.
