iinet are USELESS!!! I have a faulty UNI-D port in my NBN box which just so happens to be the #1 port...I was told when signing up that they would be able to assign me to a different port on the box and now 5 days in to paying $100 for a new service I'm now being told it's impossible to be switched to a different port..10/10 would NEVER recommend iinet to anyone.
