So I get to the page where I click whether I want Billing and General Support, Track your order, Technical issues and Sales but when I click the links absolutely nothing happens. Not a damn thing happens.
Which page are you trying to load? Are you looking for live chat? The short link is http://yesopt.us/chat2us
And it doesn't work? That's strange - it works here!
Maybe try another browser if you can, or even better use the My Optus app on your phone if you have it?
If you're trying to access Live Chat from a PC, you'll need to ensure pop ups are not blocked on the web browser. From your mobile, you'll need to jump on to the My Optus app to access Live Chat.
