Terrible/Horrific Service Rendered by Telkom

I've requested my Telkom Landline/ADSL line as well as the cellphone contract that's linked to that same account to be disconnected approximately 6 months ago. The only active accounts to be continued as per my request were the 2 Telkom mailboxes for my emails.

To date only the Telkom/ADSL line was disconnected, my 2 mailboxes are active (as per my request). I'm still being billed for the cellphone contract linked to that account and I cannot send any emails from my mailboxes after contacting the internet department on numerous occasions. Service Delivery/Customer Service is non-existent. Telkom contact me urgently.
