Best Fibre line and support..
About 5 years back 2 of the main fibre providers dug our street to lay cables, One was Open Serve, Both providers laid the fibre a week apart, 
When I tried both sites coverage, my area was not covered yet according to them..
I was so eager to connect because Iburst was discontinued then, 
I asked my current ISP , stating that on OpenServe map my address is still Under construction, But I see them finishing and leaving..
They checked from their site and told me I can get connected....(By the way Vuma only came to my address to advertise their NEW service 6 months later)

Since I ordered service trough my ISP Infinity Fibre, back 4 years ago, I had great service by Line supplier Open Serve(Telkom).
When I ordered the service, My ISP said that it takes between week and 14 days for physical installation of the fibre line.
For my surprise, Next Morning my wife phoned me that there is a Van at the gate do I know something about it, I said Might be for the installation, But that early?? I could not believe it.
The technician was professional, He pulled all the cables to the house to where I required to be, and only obstacle for the connection to go live was the access to my neighbors property . I organized with him to get access next day, The technician arrived in time as agreed, Connection was made, and I was live in 2 days..
I know they receive lots of backlash but I think we nee to give credit where is needed, I only had good experience with Open Serve.
Ever since, for more than 4 years my line was down only 3 times 2 of which was for about a hour each and sorted itself without my intervention,( I suppose was global issue).
Once my router was showing red meaning my physically connection is down, I reported it to the ISP they respectively escalated it to OpenServe, Next Morning I followed strait with OpenServe, I quoted my devise ID, and I've been told the technicians are on site, They traced the fault at a exchange at suburb level, In next hour or so I was Online again..
During Loadsheading I have a battery backup for my CCTV, and routers, and Fibre line is always On.. This is what one expects from decent provider..

Reading on Facebook the horrors of the customers of your competitors , without line for months and no one responding, makes me feel I did the right choice..

Thanks Guys for the superb service and support. Keep it up, Prove them wrong :-)
