Vodacom Sucks. I buy Data and airtime but 9/10 times I have no reception or network. Vodacom always has an excuse. If it is not the towers, it is something else. Yet at the end of my 30 day period, they take my remaining data back. Or should I say, ***** it back. Airtime disappears mysteriously? Whwn I buy food or petrol, Shell or Woolies do not come at the end of the month and reclaim the remaining food or petrol. I thought that there was a legislation passed in this regard, however we are still suffering at the hands of these Multi Billion Rand companies. I am mortified at this ****************. And try and call an agent...impossible...they have now introduced a Robot to dwal with your issues which never get resolved...
