BAD SERVICE R10 000 CLUTCH BILL

I bought a car this year June polo 1.2 GT 2014 Model pre owned and it had 36 000k on it and know it has 41 000 .The car has an extra 5000k on it .I have had the car for almost 5 months 4 because it the beginning of October my car broke down on my way home took to vw and the said my clutch was burned and it would cost me 10 000 to ix it .I called my dealer as I wanted to dispute this and I spoke to the sales manager and eventually the principal dealer Karen wood who was very rude and told me they have a 30 days warranty and this is wear and tear that they will not deal with .this is a big company and I feel they are trying to cheat me as this is pre owned and they need to foot some part of the bill .my car cant have a 30 day guarantee as its not a microwave .McCarthy end is unprofessional and they are cheats .taking advantage of people .disappointed on my way to the taxi rank while the guys in the dealership are driving home comfortable .I would advise anyone to buy used cars from them so much for a reputable dealership .
