Lies when buying car

I bought vw polo in 2015 and they told me the car is under service and warranty but it was blasted like.The fat white woman as stated me with finance.Today the car overheated at 115 000 km.This means they sell accident damaged cars cause the guy from vw cape town told me the car was in accident and repeated.I urge all customers DO NOT BUY CARS IN NISSAN PAROW,THEY ARE ALL ****** AND FRAUSTERS SKELEM
