Ford Waranty does not want to pay

Just bought a brand new Ford Focus ST. At 6000km the clutch started sticking. This happened whilst driving without having to engage the clutch. Bad smelling clutch with smoke and no power. Took the car to Ford The Glen who told Me that they will have an assessment done. After a few days they came back to Me and said that I had to fit the bill of R27 100 as it came down to \Drive style". Took this up with Ford SA who said that there was nothing they could do and that from the report I have to replace My clutch. I have been driving for more than 10 years and have never had to replace a clutch and especially having being a problem whilst driving"
