Poor service on my cell c account

<p>On the 17/09/2016 at 16:56 I called in to cell c call centre to decrease the limit on my account, but to my surprise it was actually increased to R100 and it was not what I had called in to request. My line is now suspended and I refuse to pay for something I had corrected months ago. When I went to a cell c store in Germiston golden I found out that my line is actually charged twice the amount we agreed on initially. I fear my account is being tempered with without my knowledge, could this matter be thoroughly investigated and tape recordings of my conversation with the agent I spoke to on the 17/09/2016. My contract number is ********** 972 and my contact number is ********** 871</p>
