Telkoms hopeless Fibre connection service

I have an existing ADSL line contract with Telkom. I have been trying for 2 months to get this contract changed to a Fibre contract. But Telkom issued a works order for the connection to Vumatel for the incorrect address, and despite numerous followups from my side, and numerous promises from Telkom to call me back with feedback, I have received no calls and the issue has not been resolved. I was even told on the phone that I must sort it out myself with Vumatel, but of course Vumatel then told me that they can only take instruction from Telkom.

On top of that all, Telkom has disconnected my ADSL service twice for non payment of the Fibre service that I don't have!

This is hopeless service, and very frustrating.
