***********, pathetic, arrogant, unhelpful staff

I bought a brand new Renault and took it for service to Northcliff, with a complaint about the Stop/start function. They came out with all kind of excuses. They told me it was my batteries fault. So I bought a new battery and the problem continued. Maybe I wasted my money buying a battery because it seems like they are guessing what's wrong. Then they told me that it was made for the overseas market so I must get out of the car when I'm filling petrol etc etc etc. I took the car over 4 times there. Of course they dismiss me because I guess they only care about certain races. They never agree to give me a lift back to fetch the car, although it is not my fault that I have to bring it there, yet I know that Renault does courtesy pick ups and drop offs. Why are they treating me like this. Renault SA if your car is faulty then please refund my entire money back as what is the use of having a car which doesn't work properly?? And these people don't even care to find out what the real fault it. They just go on guessing which tells me that they have *********** technicians who are probably unqualified or illiterate as they can't locate a simple problem!!! I'm fed up with them
