Telkom Cancellation

I have a month to month adsl account with Telkom and I submitted a cancellation request on the 2nd of August. Since then I submitted another cancellation request towards the end of August. Telkom has still not cancelled my line and has billed me accordingly. It is extremely frustrating, I tried getting ahold of Telkom however they do not have a dedicated telephone service to cancellations. I finally got through to someone on a chat room and they told me that i am in a fixed term contract which I never agreed to and i have not signed any fixed contract with Telkom. I would not recommend getting a Telkom account and if you do, good luck cancelling it.
