I have absolutely horrible experience with the iinet internet service. I had naked DSL unlimited connection, there was massive speed slow down issues. I was only getting 183kbps for 14 days.
I called them up but they did not sort the issue but left me hanging on the phone for 3 times and cut off the line for 1 time. Seriously??
iinet is one of the worst decision I have made in my life.

Approximate cost: $70
