Bad Service - BMW

BMW has got the worst customer service ever. You will swear they listen to your accent, determine the colour of your skin and choose whether to ignore you or condescendingly call you "sir". For more than 2 months my car has been sitting at their Joburg South dealership and every week I am sure to receive an update that the part is on back-order from Germany and this is always concluded by we "can't do anything about it" and followed by additional costs. I have been without a car all this time and the delays lead to my insurance issued courtesy car having lapsed and the very same people who have cost this long delay due to them misdiagnosing the problem. Of course, they will not acknowledge nor accept this fact. After many phone calls with BMW Customer Service, who are not decent enough to give feedback on case number ***, I receive a call from the dealership that they don't can't assist me with a courtesy car because they don't have any. When I point out that they need to assist me, they all of a sudden have 4 cars which are issued to customers and I should just wait for my car parts to arrive and the estimated waiting time is at least 3 weeks. All these interactions are without BMW's Temoso giving me feedback even after I left 4 messages for him and one more with s guy who's in the "Director's" office. What a bad attitude toward a person loyal to the brand, pathetic!
