Regretful of purchasing a vehicle at we buy cars

in 15 June 2023, I bought a Opel mokka x 1.4 auto at we buy cars, salesman Charlton said everything was done on the car, including service and the roadworth, and the vehicle was approved... I drove it from we buy cars Richmond store to house, then I drove it in weekends for 3-5km distance after (date) weeks, in July the vehicle shows exclamation mark with message: exchange engine oil, as well as everyday tire low pressure, one day I drove to Brackenfell it was cold weather conditions but the car engine overheated and the car was wet with oil all over the front boot.... I spoke to Salesman Charlton about these and he said I must take it by myself to one of the RMI approved workshop, one day I took it to one of RMI approved workshop, then they discovered that the vehicle was never been service. I tried to communicate with Charlton (salesman), he didn't pick up my calls, didn't answer my messages, I went to the store at we buy cars Richmond he was no where to be found, he hides himself, and the other day I went there I wanted to talk to his manager Michael Holloway, his manager check on PC for this vehicle and he saw the problems and faults that the car was sold to them with. He said he will call me and he never call and I tried to get hold of him. This manager I sent him some emails he never rep**** to my email messages.

early December the car in the middle of R27 at night broken down, and never started again, up until now I'm paying for what is not worth for me and my Kids.
