Damaged goods

I bought a vehicle and it got delivered on 21 January 2017,everything was hunky dory until I heard a screeching sound from one of my front tyres at the beginning of June. Only to find out that the break pads and discs were completely worn out. Barely 6 months and less than 10 000ks having driven the car I had to replace those things. People drive for years without replacing those parts. Auto pedigree Bloemfontein told me it's my driving style and they can only offer me R200 worth of fuel. So I drove all the way from Joburg for a slap in the face disguised as compensation? Surely these kind of things should be checked and fixed before a sale is initiated especially for a so called demo vehicle. I'm so appalled by this kind of service
