Thanks - I asked CR for reimbursement according to the Mennens formula. So it took 4 months for them to let me know I spoke to wrong people. As the BA GGL priority email, told me to talk to CR, I will go back around the merry go round. And will call the Manchester team....
Funny you ask about comments in the PNR - In this case I could not, as I was shoved a SQ BP and told to go away, and SQ of course wanted no discussion (why should they). Incidentally though, on my next flight (SIN/SYD again) they knocked me down to J, while leaving my kids in F (told at the gate - same PNR!). In that case, I refused to board until they wrote exactly what I wanted in the PNR (the GA had to phone for permission!). Needless to say there was no issue in prompt follow-up compensation.
Thanks for your help, as always.
