Vodacom Top Up Red Contract - Misuse

I have been in a dispute for 4 months now with Vodacom making mistakes on my contract deal that I signed last year July. I am being charged for data fees but they cant tell me how much data I am being charged for. I have been a client with them for 16 years and think this is a horrible way to treat loyal clients. Also, they logged the wrong contract to my account and now I have to pay for mistakes made from their side. Today alone I have spoken to 6 different people at their 'customer care'. My accounts are suspended. One of these numbers are being used by my mother who is almost 60 and at the moment traveling on a dangerous road and I have no way of being in contact with her. The supervisor at the call center were suppose to phone me 2 hours ago, when this did not happen I phoned back and they are not available at the moment as they are now in meetings. In the mean time I buy tickets from Vodacom that they just don't activate, but that is okay!! Customer cares words were they are charging me R4 000 but they can't tell me how much data was used and it is my right as customer to ask for full disclosure of information of what I am paying for. I also need my phone for work as I am HR at a big company. I cant work with useless service providers anymore!
