Bad service

Good day

I've signed a contract form on 2021/11/11 to do a trade in for the vehicle that I'm driving. Yesterday 2021/12/25 at about 17:00 I received a call to get the vehicle at a certain location and upon arrival I've managed to inspect the vehicle and guess what? The vehicle which is a golf 7 that they gave me had different lights, dents, it's been in an accident and the repairs done on it was very poor cause i can see the scratch marks being covered in paint, but on the same note I was told that the vehicle was perfectly fine without any accident marks or what so ever. Huge gap between the bonnet and lights, wipers not working and it's raining this side of the eastern cape, spare tyre is not road worthy, the car is dirty, no vw badge in front, noise when driving the vehicle, no nut covers on the tyres, the wrong lights on the vehicle and the overall quality is just bad, but I gave my vehicle with good conditions how fair is that?...
