Thanks @AfriNatic, managed to get the ONT installed and fibre line activated yesterday.
The line speed is currently sitting around 5Mbps both up- and download; is this something that will sort itself out automatically?
Howzit -- How long does MetroFibre take to install an ONT if Fibre is already in the building?
I ordered a migration through Afrihost on 22nd June for 6th July, MetroFibre apparently assigned an ONT Installer on 29th June. I followed up with Afrihost on 7th June as I hadn't been contacted...
