Cant seem to get rid of my ADSL

I recently had fibre installed at my home so proceeded to cancel my ADSL. However, this has proved to be far more difficult than expected. I first visited the telkom shop on the 3rd February at The Glen. However I was told by the consultant that they are unable to cancel ADSL. Instead they arranged for a call centre to call me back. The call centre called me back in minutes, only to inform me that they arent able to cancel my ADSL. They said I should call 10213 - which I did on the 7th Jan. After waiting 20min on the line I spoke to an agent to who informed me that they are not able to cancel my ADSL but that I needed to send an email to ********** I duly did so and received a reply requesting me to fill the cancellation form and attach my proof of ID which I did. I then received an email on the 12th Jan saying that an agent tried to get hold of me to discuss my request. I dont recall receiving any calls though. I rep**** to the mail making clear that I want the line cancelled...to which I received the same auto-response email...

I feel that Telkom are doing everything in their power to make it impossible to get rid of the line and continue billing me.
