Cancelation of Telkom Service

Cancelling your land line/service with Telkom seems to be impossible! I filled the manual cancellation form and send it to their customer service only for them to tell me i need to cancel online! Why is there a manual form available then? I tried the online My Telkom log in and registered. I paid the out standing amount and waited a week until the online system showed R0.00. The system how ever said that the service is suspended and it does not allow me to select (tick) the account that i want to cancel. Now how the **** should i cancel the service Telkom????????????? Not manually possible and the online system does not work? And you just keep billing....... I did not mention that the service/land line is also out of order for the last few months hence one of the reasons for the cancellation!!!
