Customer exploitation

20th April I bought a car from we buy cars, 2 days later I took it back to them Springfield branch Durban I notified my salesman Mark Hawkins that the mini cooper s 2011 model car I had purchased appeared to have a problem as all the sensor light would come on and off randomly and it felt imbalanced, Mark reffered me to Platinum for diagnosis. I took the vehicle back and fourth to platinum atleast four times everytime they would tell me it was still being diagnosed, I emailed Mark asking for advise as I was tired of the run around I was being given he advised me to log it on we buy cars site and so I did soon after I was called to take car for diagnosis yet again I did Micheal from Platinum informed me he would send a quote to we buy this is approximately well into a month after initial contact driving with these problems. I was phoned by a customer care agent informing me webuy would not be covering the cost and she said she would contact head office and get back to me about a week later I'm called and informed that now the costs are being covered. I take car, I fetch it the sensors seem to be sorted but the instability is still there, I log atleast three more queries I'm called by a Kimberly Mngomezulu who now refers me to another garage and I'm told to ask for a Rahul, he diagnosis it with all four shocks warn out and he sends quote to we buy, Kimberly calls me to inform me webuy will not be covering cost as it is wear and tear and while I agree it is, it most certainly is not mine as I had discovered this problem 2 days into owning the vehicle, how could one be expected to cover a cost they did not cause.
