Long outstanding problem not solved

I complaint about a knocking noise on my Mahindra XUV at various occasions, whereby I was informed that Mahindra SA is aware of this technical problem and that other clients experienced the same problem. Attention was only given last year, after 2 and a half years of ownership. Mahindra SA instructed the service agent to replace the shocks. The problem became more serious. Complained again, referred to another service agent. The problem were still not solved. Complained again, was referred to another service agent again. They confirmed that the shocks were not fitted correctly, the dust covers were not replaced and the coils started to leak oil due to the shocks not being fitted correctly. The response: they are no longer prepared to assist, I have to solve the problem at my own cost. I refer the matter to the MD and was requested to bring the vehicle in for a report by a wheel alignment Centre. I confirmed that I had replaced the tires in the meantime and got a wheel alignment report, which I send to MSA. It proofed that the wheel alignment was not according to the prescribed standards. The result no further support - No warranty. Problem existed long before warranty expired.
