Bad after service from Auto Investments in Middelburg Mpumahlanga iddelburg

Bad after service after buying a vehicle at Auto Investments in Middelburg Mp.I am so disappointed by this company..If I knew what I know now I would have never bought a car with them.I have my car for 2 and half months now.But still no Contract..I took the car back 6 times already and every time it comes back with the same problem.The back seat sensor is giving problems .The brake disc was damaged after they changed the tyre and never replaced.Still no spare key and sales contract untill now.I will not refer anyone to buy a vehicle by them .
