See an attorney.  See if you have a local attorney referral service.  Here in Houston it costs $20 for their first half hour consultation when they hook you up with an attorney, after that it costs whatever their regular fees are.  Definitely worth checking into to see if indeed you have a case, $20 is nothing.

Use this web site to find an attorney in your state that will probably take the case on a contingency basis (no money out of your pocket up front):  http://www.consumeradvocates.org/
