Stories since end Oct 2015 and line still active

I have sent my cancellation to Telkom at the end of Oct 2015. I was told that my SP must cancel the ADSL line first before Telkom can close the line. 4 Dec after confirming that SP closed my account I've sent the form and my copy of ID to service cancellations. On 4 Jan my line is still active. I call 10210 and they told me I should have send the forms to TOC Escalations. I did this only to receive a SMS saying they are coming to my premises. I called 10210 again to be told that the mistake was corrected. Now today I receive a call from the technician wanting to come to my home to install something. I asked him why he wants to come to my home when I want to cancel my line? I don't want ADSL neither a Telkom Phone line. I want to close everything. He hang up. I am now sick of keep paying for a service that I don't want anymore. Please closecancel my line!
