Cancellation Of Contract

Good Day<br> <br> I requested a cancellation for one of our Mobile Data lines with the following number *** the original email was sent on the 3rd of November so it can be cancelled and converted to a prepaid on the the 30th of November 2015. I ended up send the same email 3 times on different occasions since i was not getting a response from Telkom Mobile. Before month end of November I called the call Centre to find out if cancellation was loaded as requested and to my amazement no cancellation was loaded since the agent I spoke to said he was not seeing any email sent. And now this month I'm being billed a rediculous amount which is not fare and I'm requesting this contract to be cancelled as I requested in November . I have called the call centre and Spoke to a helpfull lady by the name of Sandi who logged a Case for me and here is the case number ***0. Please assist as i don't want this debit order to go through<br> <br>
