The glitch is shiite - I truly understand that the Op should be peeved. But that is Qantas, and pretty much everyone else.
On the other hand, the annoyance is because one did not get what one knew one shouldn't.
Hmmmm....
All you IT gurus should know how Qantas can prevent what seems to be a common glitch.
Specifically to the OP, yes, feel unhappy, but then decide if you want to waste emotion on fighting - many others have tried and failed....
P.S. that you did not get police called or get banned shows, as per your initial post, some restraint. That is excellent. Asking to be given the gold will just infuriate you more. Best case, IMHO, is that you get lounge credit or similar.
