No feedback at all.

I have logged a query with one of Vodacoms consultants via the call centre. The Consultant Dineo Mbezi. I have sent her several email regarding my account and she has not responded since last week when I sent her the email. I sent her 3 Follow up email requests to no feedback regarding my query. I do not know where to go anymore with vodacom because it has become a hassle with these bills and accounts that they are not transparent about. Their system issues and consultants cancelling things without my knowledge has brought on unnecessary complications which I am trying to resolve and for the same reason I am sitting in this situation is because vodacom consultants does not give feedback and just leave these queries hanging and I do not know where to seek help anymore.
