We were with Adam/IInet here in SA. They are the worse. We were with Adam for ten years, since IInet took over they have gone to the dogs.
Took 2 months to get the NBN connected via IInet, then they couldn't give a time frame to send out a router. I gave their $69 a month 12 down & 1 up the flick it was no faster than my previous ADSL2.
We are now with Boom Broadband, Aussie owned and you speak to an Aussie within 1min of calling. $79 per month, unlimited data, 25 down & 5 up, no contract $100.00, router $89.00. Its been 1 month, all good and fast so far, as long as we have power
