Telkom 'Preferences'

I was just called by a Telkom agent and advised not to go with Vox Telecoms (with the line through Telkom) as Telkom does not provide support to lines where the data is not through Telkom as well.

I was told they make support difficult for these lines and prioritise lines where more money is spent and where you purchase all services through Telkom (even when Telkom is a lot more expensive).

This seems like Telkom is going back to pre-school rules here. My advice is to avoid Telkom completely when installing fibre and look for any other provider possible as you will find it cheaper elsewhere with better support no matter what type of customer you are.
