Cancellation of Landline / ADSL Nightmare

I have been trying to cancel my Telkom Landline and ADSL line since 05 Nov 2015. I submitted the cancellation form to [Email Removed] with all the requested supporting documents and received the auto-generated response. I have sent 5 follow-up emails with no consultant contacting me as indicated in the auto-generated response. Today I received an invoice for 08 Dec 15 - 09 Jan 16. The call centre on 10210 is not able to help me and referred me to call *** to speak to someone called Khuselwa as they should be dealing with my cancellation. When I final get hold on someone, they refer me right back to 10210. 10210 then tell me to email ***,za from which I only get a bounce-back email. In the mean time I now have to pay for a service I have been trying to cancel since 05 Nov 15. I need an urgent answer to Telkom to finalise this matter.
