Vodacom service

Vodacom cannot do a simple upgrade. 2 weeks and still my issue not resolved. Managers promise to call you back and nothing. Then you get told that they are all gone home after 5pm and no one can assist? Really? Who operates a business like this? And we are paying for this? No customer support whatsoever. And we call on weekends and still no managers or someone higher to speak to? Utter nonsense really. Nobody seems to know what's happening. Please employ people that wants to work. People like us are looking for good jobs, to really give more than our best, and help others. Yet, this is what we have, imagine, really very frustrating. Shouldn't even get a 1 star rating for this
