Cancellation of landline

Hi, I have contacted your call centre on 14 November 2017 to cancel my landline and ADSL service because our complex have installed fibre. The service agent told me that I have to sent an email to ********** because I can't speak to an operator for this. An email needs to be sent to this email address. I have then sent an email to that email address on 14 November 2017at 17:42, requesting my service to be cancelled. Now I keep getting statements from Telkom when this landline should have been cancelled, and nobody can assist me at your call centres, which is bad customer service. Why can't I speak to someone about the cancellation? Why do I every time have to sent an email? It is as if you guys don't want to cancel lines and keep collecting money? I have also contact ICASA about this, and they have advised that if I can't clear this up with Telkom and this is rectified, then I can lodge a complaint with them, but I need a complaint number from you, which they will then investigate. Please can you sort this out and make sure that this landline is cancelled, and that the account is rectified and credited. I don't use this line or the service since 14 November 2017, because we have Fibre in the complex. I will also adjust the rating once this is cleared up and fixed. Thanks.
