Just Bad Service at this dealership the new name CFAO motors

I have had numerious problems with my servicing there and it still got worse over a period of 1 year. First problem was my airconditioner pipe broke, because of the rough rods driven. The second time was the brake fluid cap was left off and lucky for me it was pinned between my bonnet and my wind screen wiper. The third problem was the wheel nuts in which they were stripped and they did not replace all of them but a few and the state on them after the car had been washed. I had sent a letter to them and till today i have had no correspondance from them.
