Paying Double for no service

We have moved to a new address, and wanted to move our – fiber adsl line, when I phoned Telkom they informed me There is no fiber at the new address, we need to apply for a new line. I told them I will not be able to pay for both lines as we are not using the fiber as fron 01/09/2018 because there is no fiber they informed me the fiber line will be cancelled with immediate effect. This has not been done yet and I have already Received a sms stating that I will pay pro rata for the new line from 03/09/2018 how can this be the new line has not even been installed yet, the technician Has not even pitched on 06/09/2018 the date given to install the new line,
