A few points
1) most FF members are not active QF customers in the traditional airline sense - they have just signed up to a frequent flyer program and likely not sat in a QF seat recently or only very occasionally.
2)Customer service issues are nothing new for any corporate entity. There will always be those who are/will be negatively affected.
3)QF appears to be very successful as an operating corporate entity, so any activism is unlikely to garner much traction
4)I am not sure where "countless" came from. You actually need measurable metrics- such as waiting times on phone.
5)Why do people believe marketing or advertising promoting nebulous concepts such as " I still call Australia home"?.
6) QF is not the only operating airline
Australian based call centres?
One question: how do you know that the person you talk to at a call centre is based in Australia?
