Casseys Ford Benoni - Worst dealership ever, they deserve The Onion Award!!!

Oh my goodness, what an absolute nightmare of after sales service that I have experienced. I purchased 2 vehicles from Casseys Ford in Benoni a year ago, from what I experienced with the mediocre sales service, I guess I should've known better. When the first vehicle was due for its service, once I booked it, I received an sms with a totally different surname. When the vehicle was dropped off I notified the service department of my surname and advised that they needed to update it on their systems. Well of course when the next vehicle was due for its service, I made the booking and received another sms with the incorrect surname, I advised them again so really don't know if this has been updated, probably not. I advised them that I also had a problem with the buttons on the steering wheel, so when trying to make a phone call it turned the volume of the radio up or changed stations instead of making a phone call. So when I went to fetch the vehicle, they had fiddled around with the steering wheel, I was then advised by the service department that my steering wheel was lose, well the only way that it could be lose was that there was already a problem when I purchased this vehicle. I then took the car back a week later, to now sort out the steering wheel issue and was told it wasn't lose by someone else, do the staff in the service department actually know what they are doing? I had to wait 30 minutes for the service manager, they had taken my vehicle inside so had to bring it back, the gentleman that drove it, got out and don't ask me how, managed to rip my key ring off the key so that broke and all I got was "oh dear your key ring broke". I eventually told the lady in the service department that I couldn't wait any longer, she took down my name and number and said she would call me so that we can book the car in, that was over a month ago, I'm still waiting for that phone call. I eventually called back and spoke to the service manager AGAIN, we arranged a date for me to bring the vehicle back again. They had my vehicle for the whole day and I was told by the service manager that they would need to change the mechanism on the steering wheel. Additionally after the first service, my car has been leaking oil, that doesn't really seem to be a concern on their part. I was advised by the service manager that he would call me when the part arrived. This didn't happen, so I called on Monday morning and was told I would get a call back, that didn't happen either. I called this morning to speak to the dealer principal, he was in a meeting - they have many meetings, always have to leave messages, they should consider having a meeting about AFTER SALES SERVICE, as quite frankly, it doesn't exist at Casseys Ford in Benoni. I would also like to see what their wash bay looks like, does it actually exist? My car was filthy when collected after the service.
