The neverending VODACOM nightmare

The Vodacom nightmare continues. Agents **** to me in order to get a sim only upgrade out of me, after fighting to get the upgrades reversed, I am now unable to use the VAS I used to have on my contract. This morning I was cut off in the middle of a whatsapp BUSINESS Call and I'm now also suddenly unable to top up my data. I am also being held ransom by Vodacom, since one of my lines have a "Technical error", it had to be referred to "IT" to reverse the upgrade. That means that I cannot even cancel my lines, since technically I am not out of my contract period. I have made countless calls, spent many hours on the phone trying to resolve these issues and I'm no closer to a resolution. Just being passed from pillar to post. I have tried to get through to the number of Shameel Joosub (CEO) but no-one is willing to give me the number of his offices. I am frustrated beyond what I can express and feel powerless against the VODACOM BULLY.
