Bad Service

ever since I bought this car I've been servicing it at Arcadia VW, it has been a nightmare. my car was kept for 3 months just to fix the air con and I reported the matter to the principal dealer by the name of Delport, the car was fixed within a day, this time I have tried to fix my front left suspension for over a period of 3 months without success, I asked the service manager to arrange for me a courtesy car for more than a month without any success. Just for me to drop the car and for them to have enough time to fix the problem. The car has been in for more than four times for the same problem without any solution or help, today I have again took in the car for the very same problem and I just received the car the way I left it, brakediscs are worn out, bending lights are faulty they were just left like that. Every time I took in the car I must be absent from work because of transport, the car is stuck at home because I'm scared to drive this car in such a state, I regret my choice of spending almost R450 000 to by this VW car, I will never ever set my foot in any VW dealership to buy any of their brand. I'm spending money and time going up and down fixing this car,
