In order to prevail in any legal action you will need to be able to prove fraud. If it were me, I would be gathering all the evidence you possibly, can, get written statements from the independent shops you have been dealing with, lots of photos, then find a good damages attorney and spend an hour going over everything you have with him or her, and follow the attorneys advice. I can't say for sure, if you have a case or not, but a good attorney could probably give you a pretty accurate assessment, and a one hour consult will not break the bank.
