Still Being Charged 3 Months After Cancellation!!!

I cancelled my Telkom landline number in June yet they are still debiting my account! <br> <br> I phoned in August to query why they are still debiting my account and they confirmed that I did indeed cancel my account in June and that they would refund me the money they debited after cancellation and I see again this month that they have debited my account again.<br> <br> This is absolutely outrageous! I want my money back and stop debiting my account! Disgusting!<br> <br> The landline number that I cancelled is ***.<br> <br>
