sorry to hear the dude..
I have had my car in to get the aircon fixed. which was done perfectly.
Then I had it in to get paint chipping repaired, which was also done under warranty. I had some damage to the lower front of my bumper so the resprayed it for £50 for me (never charged for paint, just labour.. filling smoothing etc)
the had the car 3 days to do that but I got a 1.2 courtesy car which was a little dirty on the outside but other than that in perfect condition (1000 miles on the clock).
when I went to pick up my car from them the had washed it, hoovered it and even painted the tyre walls black..
whenever they said they would phone me back the always have.
Guess I have either been lucky or you have been unlucky
