Horrible service

I booked my car in for a faulty airconditioner, I was welcomed by a very friendly lady who did the car inspection and told me that Ms Prudence Molapo ( not sure about surname) will be my service advisor. She will be giving me an update regarding my car. This was on Tuesday morning around 7am. I then received a call from Mc Cathy midrand telling me they have just finished the inspection and they saw a glass chip in the windscreen should they fix it, I said no as I felt the airconditioner is priority. I then received a call around 15.20 from prudence telling me my car is not ready for collection it will be ready on wednesday, I said ok. On wednesday I didn't hear from anyone up until I called this was around 3pm, I spoke to Prudence wanting to know the status regarding my car. She told me the car is not done yet but it will be ready by 17h00 , she is still busy negotiating a quotation for a part that it needs. Around 16h00 I received another call from the lady who booked my car in saying the parts arrived late thefore my car won't be ready for collection on wednesday. She will make sure that it gets done first thing in the morning on Thursday. On Thursday I don't hear from any of them up until I started calling around 13h00, I spoke to Prudence who didn't even know what I'm talking about and she told me there is no record of my car being booked or any work done in my car. I should come in do the paper work so that my car can be attended to. I was furious, this is after my car spent 3 full days at their dealership without being attended to. I have 2 kids that need to go to school and me travelling to work, so the inconvinience and additional costs incurred were all for nothing as my car was sitting at ford piling dust. I then went to ford demanded my car back as no one could give me a proper explaination for all the inconvinience mentioned above. The service manager just told me my service advisor is on leave so I told her I am only there to collect my car as they clearly have no intentions of fixing it. All she said was I can book my car in for some other time no apology for any inconvinience or reasonable explanation of what happened.
