I have the same issue. I noticed that all my points had been stolen from my account within the app. I could also see that my email, phone number had been changed and I couldn't log in on desktop. I called them, they suspended my account and its now been more than 30 days. The part that frustrates me is that I alerted them, and now I am further punished by losing all ability to earn points, pay with points, upgrade to business for free etc. I have lodged a complaint with Fair Trading so hopefully they will help. In the meantime, if you are a platinum customer, contact Qantas and they will accept you as a Gold member. I am voting with my feet but I also want what is rightfully mine.
