In terms of arbitrating separately against USAA and Experian, I agree 100%.
My longtime attorney passed away last year. He told me to invoke the NJ CFA in any consumer contract, including banks. His reasoning was that most out-of-state lawyers are unfamiliar with its provisions, and would be scared off by the specter of treble damages.
I agree, though, that the intent of the law seems like it applies more to retailers than banks. And yes, "learned professionals" are definitely excluded (including insurance agents).
As far as I know, the advantage of the NJFCRA is that cases cannot be removed to federal court if a consumer chooses to sue in Small Claims or Special Civil Part. I'm not sure, either, if NJFCRA and Federal FCRA claims cancel each other out.
After reading your comment I wondered if there was something more to including the CFA in litigation against banks. I found out that state laws are generally applicable to federally chartered banks as long as they don't conflict with the National Banking Act; and that claims of unconscionability, lack of fair dealing and the like are common reasons to include the CFA in a complaint.
Of course, my goal is to reach settlement before they even see a complaint, because JAMS requires the bank to pay up front after receiving the Demand for Arbitration, but before the plaintiff serves the complaint. Only time will tell.
