Telkom fault and Ongoing bill issue

The fiasco started last year. I made a request to stop the added services to my voice line as I had been paying for it for a year without an actual telephone. I did not want the landline disconnected or my adsl service. However everything was stopped. An extremely rude and ******** staff manager at Canal walk who couldn't understand the difference between a land line rental and an added promotional voice service attached to that line refused to help. Numerous attempts and promises from Telkom to revert back to me never materialized. They then billed me for services after the line was disconnected citing 'notification fee' even though the fault was on their part. Still receiving promises from Telkom to get back to me but it never happens.
