MINI of the Main Line

We have not owned our 2008 Mini Clubman for more than 2 months and have tried 4 time to get an accessory (chrome pedals) that was owed to us from the time of purchase installed at the dealership, each time there was a problem even though they confirmed they had the correct part by e-mail & phone and we drove an hour to get there to be disappointed. The 4th time over a month and a half of trying was the topper, they once again messed up the order and offered us a complimentary tank of fuel while taking our car to get fueled the service tech got in an accident and totaled our car. We never gave the dealership the ok to remove the car from the lot, why would they if they did not do any service? When asked at the time to speak with the service manager we were told he didn't want to talk to us? Was he kidding, 4th time and all they can say is it won't happen again.. What if it was a major problem, how long would it take to get the parts correct? They are right, we won't be back, and we are heading to OTTO's in West Chester.
