Uncontactable/locked account

My contract has been locked by Vodacom, through no fault of my own, due to Vodacom's own stupidty, now I have been trying for more than an hour to get through to them, to get this problem sorted out, & I end up holding on forever, without any results. No answer, no comeback, no help at all. Seriously people, no wonder I want to take my business elsewhere, if this is what I'm going to encounter all the time.
