Billing Issue

I have given my required 30 day cancellation notice as per reference ***A & ***A. The lady whom assisted me at Clearwater Telkom (Lebo) 08/11/2015 clearly advised me to pay the last outstanding bill the end of November, which I have done. It is 03/01/2016 to date I have been struggling to get his account closed and confirmation but Telkom ignores all my emails that I have sent to get this matter resolved. I have kept to my terms and conditions and now Telkom is playing games with me. I cannot afford for any further delays, and needs resolution of the matter urgently.This account should have been closed in your books the end of November as per my request , so why do you still send me statements and why do i not get any form of feedback
