Telkom stopped service, but I pay for it.

I have logged an service error on my ADSL line, but was informed by Telkom agents that the service will not be repaired as Telkom are going wireless and are replacing the copper. I have requested a refund due to no services are being supp**** by Telkom but was informed that I should give notice. What a joke. Telkom stopped the service but I must give notice and pay for another "cancellation" month. I would like Telkom to just give me the credit for the service not supp**** and close the Telkom account as they are not providing me with the services that I have signed up for.
