Australian Support Lines - Constantly Busy

I've been trying to call the Australian customer service support line for over 3 days now to rectify an account based issue so I can transfer a character from one account (raf account) to my main account. I've emailed customer support in regards to this issue and they told me to ring the support line.

The number has been constantly busy for 3 days, and because the Australian support line apparently runs on pacific time, it means I get around a 4-5 hour window to call it.

If there's a lot of people on the line, that's fine. At least introduce a phone queue system so that I can eventually get my problem fixed and not have to constantly get up early for no good reason. My problem would probably take a good minute to fix at max, it's irritating to have to wait days on end with no progress.
