If you are not satisfied... just go up the chain of command. It works.
I bought a Chevy pickup at a Pontiac Dealership once... the dealer said to me "The carfax came back good"
When I got home... I was curious about this whole "carfax" thing... so I logged on, paid $20 or whatever it was to join, and looked up my new pickup.
The damn thing said "Potential odometer rollback"!!!
I contacted a co-workers mom who is a friggin' badger when it comes to dealing with things... and I had HER call.
She call them up and says "I'd like to speak to the owner"
They said "He's not available, can we take a message?"
She said "Sure, tell him this is _____ ________ on the phone with _________ legal services (which was her business) and we would like to speak with him before we go public (local news agencies) with the fact that his dealerships are rolling back odometers"
She got a call back in under a minute from the owner who was on vacation.
Turns out the truck had something funky going on with the registration from another state, so when it came to CA, and then went through registration, the odometer readings didn't make sense. Everything was on the up and up, and they offered to buy it back... and when I said I liked it and wanted to keep it, they gave me a free 2 year powertrain warranty and a bunch of oil changes and tire rotations for my worries.
My point is... if you don't get what you want, go over that person's head... they have regional managers and departments to deal with these sorts of problems.
