I have changed many providers but always had issues with speed and cost (i was with slingshot before:- horrible speed trust me)then i moved to orcon that was even more worst, but i was happy with Nznet from last 9 months, it was always good for me,
I guess every business has a bad time, but we should learn to trust.
I agree, I've been on Telecom Big Time, Telecom 20gb plan, Slingshot Unlimited, WorldNet Unlimited and NZNet and all of those providers before NZNet sucked in terms of speed. Maximum 100kb/s for a download even though the line speed was reading 8-9mbps.
With NZNet on the very same line I get 15mpbs sometimes and stuff actually downloads at a rate that it should (1mb/s).
