HORRIBLE PEOPLE AT INSPECTACAR CENTURION LIFESTYLE

I bought a dodge journey in November 2018 and in January 2019 the car started smoking in the bonnet while I was driving, I took the car back to inspectacar in lifestyle Centurion. I was told they can't take the car back as Iman the owner is not in, had to drive the car back home while putting the water in every 5km. I took the car back the next day and the said they will send it to the workshop and I explained I'm a sales Rep and I need a car while they fixing that and again Iman said to Mike the guy who sold me the car they can't assist me with the car. The car was fixed 3 weeks later and in January 2020 the car just stopped in the middle of the highway and the mechanic said the engine has seized and needs R58000 for new engine, it was clear that inspectacar sold me a car that was not in a good condition now they ignoring my calls.i am stuck with paying a car I don't have
