Optus on-hold time

I was relocating my homephone (with Optus). Local calls work but I cant call mobile. Everytime I call the customer service (mentioned in the phone bill) - I was either passed around to various different disconnected departments or was being on-hold for 45min+ - Yesterday I'd like to find out how long my call finally was answered by human, and it took them 1hr 25min. Even after that long, the Optus rep (it was Mac, and then transferred to Brian) - asked me to 'hold for 30sec' and then the next thing that happened, I got transferred to main reception (with computer voice recognition to select which areas of enquiry) - at this time i had no more energy left to continue.
