Cancellations of service

Good day. I phoned Telkom on the 3/10/2015 on the 10210 number and chose the account/billing option. I wanted to cancel my voice call line and keep my ADSL line. The operator informed me that its only the weekend planner that can be cancelled and as it was part of a bundle all services will be separate now as I still need to pay for line rental for the ADSL. So we did it and she said its all fine. So now I received my new bill and I am billed for all the services at the higher rate separately and again I am billed for the weekend planner. I phoned 10210 again and asked why it is still appearing on my bill and she said she can't see any cancellation. She needs to send my a cancellation form to be completed and I need to email it back. So that means the cancellation is only going through this month if I send in the cancellation order and I have to pay the higher rate. I am sorry but I am not paying for a service that I thought that was canceled a month ago.
