Is customer service dead and buried in SA?

I’m still waiting for a promised apology from Discovery SA for shoddy service; a friend of mine is still waiting for an apology from Weylandts for damaged furniture; Bathroom Bizaar in Fourways charged the same friend more for delivery and installation of a shower door than the entire product cost; Imperial Select, Boksburg, sold another friend a car which was supposed to have been passed by AA, when it in fact failed, and the airbags detonate without warning!
