Vodacom Denial and Extremely Rude Agents!!!!

Clearly I am not able to update my previous review on Vodacom, as they posted a "Private" reply. Which is *******!! An agent did phone a day later (despite the urgency of the issue), and kept denying everything, and twisting my story, and basically insinuated that I was a fault, and that their "security" questions are approved by their legal team. Note that my ID number, bank and type of account and email address are NOT really private/personal. Just about anyone knows these. But Vodacom couldn't care less that details on my account were changed (they completely deny that ever happened, etc, etc. as there is NO log on their system), and also couldn't care less that someone tried to do a SIM swop on my account. Yet, the SIM swop was initiated & approved internally by Vodacom or an agent of Vodacom. Which all of these people know my details as well. Then the agent who phoned me kept interrupting me over and over, and when I asked him to stop doing that, he just said I was interrupting him as well. Point is, the agent was extremely rude and unhelpful and completely denied Vodacom involvement, and refused that Vodacom will do anything about this whatsoever!! They simply just couldn't give a dam!! Yet ... my account has been compromised at least twice! And clearly someone who either knows how to do this internally or not. Besides this, both my mobile, and my wife's DATA SIM are being heavily spammed by people knowing our details. We NEVER allow any company to send marketing information! Yet we get this. And to top that my wife's DATA contract is just that. DATA, not used for anything else but DATA. Yet the SMSes have her exact details. ONLY Vodacom know this. So this is information disclosed by Vodacom to 3rd parties WITHOUT our permission!! Someone is very wrong at Vodacom!! I have in the past asked that my issue be escalated to a senior person who is able to understand and resolve, and report back ..... I just get excuses, etc. It is very clearly that the agent staff DO NOT want senior management to know about these issues, else it would have been escalated. And while I'm busy, every time you make a phone call, I get a very very loud sharp double tone before it starts ringing. It is really bad when you have earphones in and on the car system!! But Vodacom also deny this!!! I honestly wish that someone with real authority and ability to resolve this contacts me. BUT I DO THINK THAT IS A FANTASY WHEN IT COMES TO VODACOM!
