Risking lives with false advertising

They don’t even deserve a star after false adverti*****t they now refuse to fix the car I bought from them each time I go to the branch I’m told to log a complaint after several complaints they’re telling me they don’t have anything to do with mechanic issues they just do sales, how does one sell faulty cars and claim they don’t know about car issues. This is putting lives in danger I drove a car with worn brakes and disc because I was told nothing is wrong with them such a selfish company 😡
