QF points in an account with non eligible activity in 18 months expire (very clear and in the t&c for many years)
Transferring points in not an eligible activity (very clear and in the t&c for many years)
So points transferred expire:- its that simple
As the OP went to some effort in get the account alive again with correct email, etc yet did not bother to read QF emails and even had 11 weeks to use them, or have eligible activity, and yet did nothing I find very strange. [Am not sure if the QF web site shows when points expire.]
OP comment "The only reason they have is because they know they would have had to give them back if the matter went any further" is totally laughable to me & many others
QF have been generous in reinstating these 100,000. Such ungracious comments put QF generosity at risk (with good reason)
