Disgusted

I visited the dunlop tonnesens branch in Goodwood where I stay to have my car fixed. The salesman who's name was Gregory was confident in explaining what the actual problem is. His confidence convinced me and I went ahead and instructed him and his team to go ahead and fix the problem. I then fetched my car and he confirmed everything was sorted. A day later while driving to work I picked up the car was still giving me the same problem. I then called Gregory and said to him the problem was still not fixed, he then asked for me to bring the car back to him which I did. They them determined that the horrible noise was coming from the front of the car and explained to me what else needed to be replaced. All I wanted was to have the problem sorted and I was prepared to pay the cost. The next day I got a call to say the car is ready. Two days later I still had the same problem and then contact Gregory and his team where I was asked to return the car for inspection. They inspected the car and made out a new quotation for the repairs. I was extremely furious at this stage because already I spent R5500 to have my car repaired. I then went to a different branch and spoke to Gavin the branch manager who identified the actual problem. Gavin was totally confused because he couldn't understand how they had worked around the problem. Gavin then explained to me it would a extra couple of thousands to have the matter sorted. I then contacted Lawrence who deals with customer complaints. Lawrence then said to me all the work they did needed to be done which I disagree with because I went there for one problem and now I'm having endless problems. Is this customer service? I am extremely disappointed in the service I received from dunlop tonnesens and I'm prepared to take this matter further. I will never do business with them again and will not refer anyone to them. Service delivery is extremely poor.
