Pathetic service from Vodacom

My fiance took out a contract for the both of us in August last year and in on the 30 June I was credited with 100 megabytes for no reason.I called on the 30 but was not assisted I called again and was told that I shouldn't use the data because I will be charged for them so the whole day I sat with no data so that this data would disappear as it was on day data mind u I was told if I use it I will be charged R38. So when my account was deducted I bounced back and I was told that I was R38 less and so I was charged R100 more because there were not enough funds in my Account.

I been calling to get this matter resolved that wen I call I'm using my number I can no longer get through to an agent I'm being told that someone will call me back and No one calls me back.

I'm sick and tired of this I want this matter solved if not there are other networks that I can take my money to. It's August now and still no one has been able to assist have reference numbers and names of consultants that I have spoken too.
