Hynudai Roodepoort

I had a bad experience ever at Hyundai Roodepoort. On 09 Mar , took my car for service which I paid R7300.. They kept telling me, to change my as it's old. 01 April. Had a breakdown in 10kms to Botshabelo. Called Hyundai, Roodepoort spoke Sizwe(forgot his name ) he wasn't welling to help. Car was towerd to Hyundai Bloemfontein. I was told they want R5000 for diagnosis. Eventually I managed to tower it to Roodepoort branch. Where I was told engine was damaged. I asked, how come when car was serviced by them.

I was told, due to skip service that why my car was damaged. How come , that my car was in good condition before service and just after a month engine got damaged?? If it's was due to service , why didn't I have issues with it's before service?

I was taken from pilar to post. I spoke to their manager Mr Nelson on several occasions and he wasn't willing to help me. Hyundai Roodepoort damaged my car and they don't want to take responsibility for it.
