Ridiculous Customer Service - "Its not their problem!"

A few days ago my car went in for a service as well as to check an error that kept popping up. BMW calls us to say they have repaired everything and that the fault is now cleared. The next day the vehicle refuses to start. After getting the vehicle back to BMW they begin to test and find that the issue is with some eaten up cables which gave a drivetrain error. Knowing all too well that this issue was not resolved they returned the vehicle to us. When we call BMW Supertech they say that the issue has to be escalated to BMW Sa when in fact they have nothing to do with it. The vehicle is barely doing 25000kms and is still under motorplan. The two extremely rude and unhelpful people where John and Thebeko - Both seriously need to go for a class on simple manners and customer etiquette.

After calling more than a dozen times, and at this point i am highly frustrated these guys persist that they cannot help me and try moving me across to another rep, I then request to speak to the manager - I am still waiting to be called back.

The crux of the issue is that they have not done a full checkup on the vehicle and were willing to let it go out of the workshop without knowing if it is roadworthy which could have caused an accident.

Furthermore, The reps have the audacity to tell me that if i want to report it and take it to the media , i must go ahead and do so.

In what way are these people of benefit to BMW???
