BMW on call: we are just a phone number, don't even bother calling us.

If I could get an answer from BMW on the following: What is the point of having BMW on call for potholes and tyre related queries, when you do not have stock of the tyres? What is the point of towing my car to a bmw dealer when one has to be in a different city the following day as one does not live in the area that the tyre got damaged in? Now, here I stand, stranded in Centurion (I live in Nelspruit). How am i going to get home? I have a job that requires me to be in at 07H00 tomorrow morning in Nelspruit. Will BMW provide me a courtesy car? Obviously not! what is the point of paying R650 000 for a name brand car such as BMW, where they advertise BMW on call and never being let down, and getting the consumer treatment of that of GWM(no offense to them, this horrid brand could learn from GWM)? No effort being made, as long as the debit order goes through, right BMW? This is outright disgusting from a brand with the caliber of BMW. I want solutions, not excuses or blame game. Sort your **** out BMW. I await your call
