Thanks for all those replies! To address each:
Yes, we are both Silver BAEC
The referenced thread only applies to Avios (unless you were subtly pointing out that my whole question isn’t beneficial).
Yes, I checked that it wasn’t the headphones.
(As an aside, I find the handset really non user friendly. Unless of course it too was u/s).
Yes, the messaging would have been useful as I was in 1K and OH in 1A. I felt really in the way ducking through the galley to visit every time.
The text I put in this post wasn’t exactly what I put in the complaint, so how it came across would have been different. I do endeavour to be precise and non emotive.
So the general consensus is that £100 isn’t great and Avios are more usual? Not sure how I might approach BA to say “I don’t want your voucher, give me Avios”
