Cancellations Nightmare

I have sent through my cancellation form on 17/03/2016 for the landline ***. On Tuesday, 12/04/2016, I received a call from Telkom saying that my line cannot be cancelled because the line has not yet been released my ISP. I have spoken to my ISP (Afrihost) who says that the line no longer reflects on their system, and when they check the Telkom systems it does not reflect that the line is managed by them.<br> <br> I spent 25 minutes on my cellphone this morning with the call center being transferred to billing, to technical, back to billing, to mobile (for God only knows what reason) and then got cut off being transferred back to \fixed lines\". This is completely unacceptable. I have lodged a dispute and will NOT be paying for ANY billing past 1 April 2016."
