service received from BMW kunene Brothers and BMW

I purchase a bmw from kunene brothers 2 months ago . My first question was , was the car in an acedent they said no only once i signed for the deal they informed me that the car was in an accident. Well i already signed for the deal so what can you do especially because its bmw you should expect good and honest service from them. I took the car to be inspected and was shown all the issues in the car . The spear key was never coded, bolts was missing on the car. Adjustments on the seats did not work as they are broken. Emailed BMW SA what a joke, i had one call after the other from different branches and call centers, after promise and another one nothing is still not sorted. Its a joke especially from a company like BMW
