Worst Service ever!

I purchased my car from this dealership in 2011 and have been using this dealership for my service. For my 45000k.m service when I picked my car up my rear bumper had been scratched against a wall while moving my car. Upon me fetching my car nothing was mentioned until I complained. They then took my car in and did a back yard job in repairing my bumper. For my 75000km service my computer box was damaged and again I was given a lame story. Today being the 19th June 215 I took my car back to get the computer box issue sorted out. I asked that my car be ready by 12:00 as I have things to do. They decided to call me at a time which was convenient for them. Then to top things off their driver left me at work for me to find my own way back to their dealership. The time is nov17:35 and I'm in a taxi on the way to this useless dealership. I would never recommend this dealership to anybody as it is the worst place to service your car and when it comes to customer service.
