Bad Service

Once again I am being overcharged on my account. Every time I call, I am given a different reason. So far I have two reference numbers but I have NOT received a call back from them to sort out. I am so desperate for help. My cell number is ***. In February I was helped by a Skumbuzo Ndlovo, from the Sales fulfilment Team. I was told that he caused the problem I am expieriencing now. I am now waiting from the 17th of March 2015 for this to be resolved.
