They sold me a scab car n ignoring me now

Baddest sevice ever and I'm frustrated 🥴..I purchased a pre-owned vehicle from this dealership (Brian Mntambo)is the sales person and from the first day I went to collwct the car I was treated like *******,I went to the dealer and the car was not ready yet I was told all will be ready n I took a day off from work ,I stayed there almost 5 hours just for collecycz they replaced the windscreen when I was there, requested the dekra report and till today I'm still waiting,4 days later the car lost power right after they took it o service n it was broken ,they came n collected the car and they told me it was the fuel pump n blamed it on us,I told them I don't want this car anymore ,even emailed the manager there who has never rep**** to my email to date,the car started having a sound when I'm turning the steering wheel fully after the fuel pump was fixed ,I thought it wasn't something concerning I then decided to drive the car to kzn and that's when the sound became worse and I told the sales consultant right there and then,he said he will book the car in when I come bck from Kzn on Monday the 30th I told him the car is back and he had not attended to me,lady night I realised the engine light popped out again n I told the sales person n took the picture but till now he has not collected the car and in all these instances where they book the car in they have never even offered a courtesy car.qjat kind of service is this? I hate the day I took your offer,a R200 000 car and it's a s**** car
