Failure to Cancel Package and Line

I submitted an online request to have my line cancelled on the 13th of October Ref: ********** 154 : ********** , I then confirmed the cancellation with a call center agent. More than a month later the line is still not cancelled. According to my calculations I only owed Telkom R40 for the remaining time and will not make any further payments. I have subsequently also filled in the cancellation form(The online method does not request this) but still have not received any feedback.
