car repair

I had an overheating problem with my car in October 2017 of which I took in to VW McCarthy Durban to sort out and I paid R3000 to have the overheating problem sorted in less than two months I am having the same problem. The agent I was dealing with was IMRAAN I brought the car back to them and told them I am having the same problem again and They quoted me for an additional cost of about R4500 of which was unacceptable as they should have picked up what was wrong in the first place. I brought the car in to VW McCarthy Durban today (21 December 2017) ALL day I did not get an update on what is happening with my car. I left it at 7 am, and I called at 15h40 to get an update and left a message for IMRAAN who was not available at the time of my call he still did not get back to me. I called again at 4pm and another agent Charlene tells me my car has been ready for collection yet IMRAAN did not update me or have a drive pick me up. This is unacceptable given that they should have pick up all problems initially and yet I brought the car back an still I get no update all day and I have to chase after them to find out what is happening with my car. I am utterly disappointed with such services as I have been bringing my car to this dealership since I had my car.
