Sold a broken car, one week later no info!

Terrible terrible experience! I was sold a car that didn't even last a week and now I am sitting two weeks in with no car. I still to this date have no clue what went wrong with the car or what they are doing to it, but I cannot wait any longer for these *********** people, I need a vehicle and I can't sit another week or two without one. I have told them that I no longer want the vehicle and will be taking my business elsewhere as I do not trust them. It's such a pity as they've completely destroyed the second hand vehicle market selling less than average cars.

Someone help!
