Immensely frustrated

I am immensely frustrated by my current situation. I received a response from Vodacom on hellopeter on Thursday 25 February informing me that a consultant would be in touch to assist. As yet, I have not been contacted and the debit order that was taken from my bank account was definitely too high. I accessed my online bill and noticed that I was charged R249.42 for my PROMO 1 GB for 3 months data, the same charge that I was informed was an error and would be removed by Customer Care. I have also not received that 1 GB of data for this month and, as I upgraded in January, I am still within the 3 month period. I attempted to contact Vodacom via live chat, but nobody responded and it eventually timed out. I shudder to phone Customer Care again considering the last call I made (the consultants had a personal conversation with each other rather than talking to me). I would really like to have this issue resolved please. Is there perhaps someone else higher up that I could contact who could assist?
