Sell cars that are unfit for the road. Stay clear

Absolutely shocking what they have done to me ! I traded in my car with 12 months mot on it for one of theirs . I also paid £600 for a car that is completely not fit to be on the road . Everything that you can think of is wrong with it , had it to two reputable garages now they both said there’s no point in even trying to repair it . I have really tried to communicate with these charlatans ( imo ) and nothing , they don’t care . I’m a 64 year old Widowed Disabled Woman . They’re absolutely so callous it’s untrue imo and that of the two mechanics that have inspected the car . Also it was advertised as having 4 previous owners but when the log book arrived it clearly states that the car has had 7 previous owners. Unbelievable. I’m so upset it’s untrue.
