Trying to upgrade without success

<p>I phoned Vodacom online on 12 Feb for an upgrade.</p> <p>When I received the quote the next day, there was an added 500MB fo R100 a month, which I had no knowledge of. I phoned back to get that removed, and since then, have phoned 5 times last week to get the "deal " through without success. Their system is constantly down, and if not that, there is something wrong with the code, so nothing can be put through. Every consultant promises to phone back, no phone calls to date. How is it possible that a huge company like vodacom, can't have an efficient system for upgrades?</p>
