Hi-Q Autowiel Menlyn. Dangerous sub-standard service.

After taking my BMW to Hi-Q Autowiel in Menlyn, Pretoria, I drove to the Western Cape. Two or three times I heard a strange banging noise. I took the car to a tyre/shock dealer in Stilbaai just to be informed that the stabilizer bar on the right front was never fitted. It was connected at the top, with the nut only hand-tightened and the bottom end was hanging loose. The dealer said I was lucky to be alive after driving around 1500 kilometers on highways and through mountain passes like that. In the left front the electronic sensor on the arm was not fitted and was loose.
