I try to keep it simple. It’s not necessarily an issue at the QF end.
Online claim? The flight(s) was probably registered / processed by BA but got stuck in the ether somewhere.
BA are usually quick but can also take 6 wks 
.
No real point quizzing them why it didn’t come through. It’s probably the BA end.
I just email saying online claim failed. Here’s eTix, BP and flight details. If you can supply all that, they usually get processed within a day or two.
Earlier this year I had CX flights CGK-HKG-LHR//MAD-HKG-DPS. The first two posted automatically within a week. The 2nd two never showed up after 14 days. Online claim failed, so emailed QFF - processed in 24 hrs.
