Incorrectly billed

<p>On the 24th of September 2016 my account was increased without my knowledge. I called to notify cell C I did not make such request. I was then given the case no. ********** 905 and informed that the case will go under investigation and be notified of the outcomes. On the the 12th of October 2016 I called in and consultant told me the case has been closed the mistake was on Cell C part she will fix the amount back to R50 and sorry for the inconvinience. My account will be adjusted to R263 that I pay each month. come end of the month R320 is taken from the account, the consultant are clueless not helping when i call in -( </p>
