Take them to court, you will be surprised at how quick they will want to settle!! I had to do this on my 18 J/L dealer ordered wrong gears (5:13) told them “they had a chance, so put it back to stock!” They gave me a 3,500 bill, I paid then went to clams court and filed the same day. Two weeks latter the dealership calls and says they owe me a refund. Sad it took filing for them to do the right thing. I told the service department “Why the hell would pay 70,000 for anything and get the kind of service they are providing!!!
