Just had a thought/light bulb moment, if you use a smartphone, one of those that can do internet on it, ie, not the budget nokia c2 sort of things, the ones without buttons I mean, and are not getting sms from QF while in Aust, go and turn off harassment filter on the phone.
I was doing some things, also needing 2fa, not with the QF website, and kept waiting very long times, and no sms, but the websites kept saying sms sent.
Go to "Phone Manager", then "Harassment filter", and turn it off, you an turn it on later after the QFF process.
If QFF uses a private number sort of incoming sms/sender from a private number, your phone might not make sms ring tone.
But if you go and have a look, under harassment filter, you will see the missed messages and calls.
Important also to note, even if your regular people who call you, might also get blocked, ...
I discovered that my harassment filter had blocked a lot of people, even those I know, and they said, they did sms me, because it (the filter) was on, and so had some missed calls too.
