ANTI-CUSTOMER SERVICE MANAGER

I have been trying to upgrade since last week, but because of system issues and extremely unhelpful and rude staff, especially Dumisa Zikalala who was rude, refused to even entertain my please for help and basically stone walled me, even after telling him that their systems are not working correctly and that I had just come out of hospital and could not go into a MTN store, he couldn't care less, the same too can be said for all their staff. This man Dumisa should not be customer facing!!!! I couldn't get through to sales, couldn't use any of their electronic channels to upgrade, NOTHING! Then spoke to a gem of a "manager" Dumisa Zikalala (apologies if I misspell) who told me there is nothing that he could do for me, HE IS A MANAGER IN CUSTOMER SERVICE, WHAT A FLIPPING JOKE! I have been a MTN customer for over 20 years, time to maybe change me thinks.
