No feedback from dealer

I'm not happy with the lack of communication that I'm getting from this panelbeater. Firstly I was advised to bring the car in before 8am on Friday (17th May ) for the repair of the rear view mirror mechanism. I have been sending emails requesting for feedback as to when the car will be fixed as I use the car to take my son to and from school. It would be appreciated to get feedback as I need to make alternative plans for my son who is writing his exam. I honestly have a soar taste in my mouth regarding my car being fixed and will also take this up with Discovery!
