Poor service from Vodacom Help Desk

I reported my poor LTE speeds on Sunday was promised that a technician would contact me on Monday to resolve the issue needless to say that did not happen. I called again this morning and was told that it takes 3 to 7 days for the technician to resolve the issue. The consultant said that she would escalate the matter and that she would send me a reference number in this regard. Needless to say I am still waiting. Come on Vodacom is this really the best you can do?
