Vw vereeniging is pathetic!!!!

Bought a 2011 vw caddy on the 30th August 2018 from Malcolm at vw vereeniging. I fetched the car at the dealership that Thursday on my way from them to Centurion i realized if i open the windows it closes them self again the aircon is not working the radio is not working and the radio. I phoned the sales guy he said that we have to book in the car so that they can sort out all the stuff. I told him that i was going away the weekend so he said bring the car the Monday the 2 September. That monday i told him i cant get off work he must sent someone to collect the car. He said his driver is busy so he will sent him the Tuesday so i drove with the caddy to Middelburg. The clutch broke and i phoned him sent him pics off all the problems that was on the car and then towed it back to centurion. A week and a half later they fetched the car after i sent mails and phoned everyone at the dealer. I drove 600 kilos with the car till it broke now they said they must replaced the flyweel end clutch and it is because off bad driving so i must pay the bill and it is not covered. I told Malcolm i want to cancel the deal becaus i had the car not even a day and there was problems he said to me things will get messy i can't return the car.
