Ask for the"top man",stare him in the eyes(if he can look at yours),and tell him it was bought and installed before it was made.Other than that,call around to other dealers and explain your situation.Don`t be a butthead,but be stern.Tell the dealer where purchased to get off their seat and stand behind their product they so gladly recieved money for less than 3years ago.
