As an academic issue, you have grounds to rescind the entire contract on grounds of misrepresentation -- or obtain damages from the vendor to cover the costs related to the plan you actually believed you were receiving.
Unfortunately, in the real world, the vendor is likely to fight tooth and nail to deprive you of any sort of satisfaction, because it's big and you're small. You could sue the vendor for misrepresentation in small claims court. That would certainly stop the argument, if you get a judgment in your favor.
You could also file a complaint with the NJ Attorney General
. I've actually had some success with this in the past, when the dispute concerns cable, dish and wireless vendors -- because there are a lot of ongoing complaints by the public.
The idea that you can't see the contract demonstrates a clear intent to deceive. Most of the time a misrepresentation claim is very difficult to make. But, you have a rather interesting set of facts here, that could give you an unusually good edge against the vendor.
