No service yet the debit orders come through

<p>In September 2016 my ADS internet connection went down. I logged a ticket in October 2016. I got no response from Telkom. I then logged another ticket on my account stating that I will not pay the debit order that will go off at the end of November as I didnt have any service and I went on to cancel my account with them. The debit oder went off at the end of the month as per normal. I had it reversed. Then they debited my account again. I had it reversed. Then again. And again I had it reversed. I've had no contact from them, they have my cell number and my alternate email address as I dont use my Telkom email address. How can you charge me for a service that was not delivered? </p>
