BKK-LHR September. Both of us had IFE not working and I had an intermittent seat issue( it still went fully flat but would randomly decide it didn't want to remain so but it really wasn't a big issue). Nearly full J cabin( only separated centre middle seats free which was in no way appealing), resets tried several times crew couldn't have done more but the CSM submitted a complaint on our behalf via her ipad. +100k avios payout ( including an insanely large apology payment as part of the breakdown). We happily accepted knowing it was well above what is normally handed out for such things. Better still the avios were in our account in under well under 2 which is a record from our own prior experiences.
