Warranty means nothing

I drive a Hyundai I20 1.4 fleet. I bought it from Hyundai in 2013 with 6000km on the clocks. It was a demo car.<br> At 15 000km they changed my radiator cap, they say warranty does not cover this, its wear and tear. <br> 15 000KM????? Now on 49 000km I have taken my car to brake center to fit new brake pads and they inform me that the brake discs are worn and need to be replaced Hyundai again claimed this to be wear and tear and warranty will not cover this. 49 000km????? Experts assure me that this should only happen on 110 000kms. Again I phoned Hyundai and they said i must bring the car in for an entire day so that they can take the tyre off and take some photos????? The car was recently in a small accident, when i approached them for a quotation for insurance, they again insisted the car be booked in for a whole day and I would have to pay between R700 and R800 for a quotation????? I took the car to one of there agents who helped me on the spot. It took him 20mins to asses the damages and I was on my way. Always being a VW driver and this being my first Hyundai I will NEVER EVER drive a Hyundai EVER again!!!!
