No Customer Care after hefty repair bill

I am very disappointed with the Customer Service my mother has received from Audi, Centurion. Her vehicle was booked in several weeks ago for repairs totalling over R 19,000. Since the vehicle was returned, it has had nothing but electrical problems. <br> It has been back to the services shop for a 'quick fix' as both the indicators and the electronic window on the passenger side were not working. This was on Friday, 30 Jan. On Monday, 02 Feb the car would not start and is completely dead.<br> My mother left several messages for Pierre on the 2nd of February and after not hearing from him, I decided to try and get a hold of him. He advised that they will send assistance to start the car at 09h00 on the 3rd of February. Its after lunch time and my mother is still waiting at home. This is the second day now with no indication when anything will be done. Their website says First Class Service, I have yet to see any service.
