Beware when cancelling a Telkom line

I have had now three occasions (business and private) in quick succession struggling with Telkom to cancel lines when so requested. All good to submit a cancellation request and receive a reference number. An automated message says that one will be contacted within a set time period. This never takes place. The line rental continues to be billed beyond 30 days after cancellation. When this is queried, Telkom's states that the final amount had not been settled at the time of cancellation so they continue billing the line even if unused because they provide a service.

I have heard the very same tale of a business that moved premises and despite them requesting cancellation of the old lines, Telkom continued billing for the same reason.

I think that this is a highly ********* business practice and unacceptable. Stop means Stop. No If's and But's. I don't know how many people and businesses have been affected by this practise?
