The email addresses are very useful, because the page on the website just invites people to call the Call Centre. I was on hold (to the CFP line too....if they're still operating that separately) for FOUR HOURS the other night (10pm to 2am) before I gave up. I see that refunds/rebookings are possible up until 31 May, even after the date of the flight date, but rather than wait for a few weeks I think I will email them now....
