Lol. Absolutely agree. I interpret all such responses as you do. I fly often, globally, and on a range if airlines, and have something to moan about with all of them once a year or so; when this happens with CX BA. EK TG LH. LX ( the airlines I use most frequently) I carefully report the incident and, TG excepted, always receive feedback on action. I do this in my own interest as
I like these airlines and wouldn't like to see standards fall.
But with each airline there is a core of flyers who accept, even defend, low
standards/ poor performance.

Recently, I complained about loud and disturbing talking in the galley during taxi takeoff descent, and landing ( I can still tell you what they all did on their BKK layover) and subsequent poor management of meal service ( definitely a one off -- first time ever on EK for me and thats why i alerted customer service) on a recent BKK-DXB flight. I got
(1) within 4 days a response saying they had launched an investigation and would revert and
(2) within 10 days a detailed response that acknowledged the validity of my complaint and informed me that the VP for cabin crew was actively
following up on the issue, thanking me for the feedback, and encouraging me to keep providing such feedback when I encountered such poor standards

In this case I both complained to the Purser ( being careful to specifically point out the one CC on rhe team who actually did perform to EK. Standards) and wrote customer service. (2) above mentioned the Pursers log as recording and confirming the service issues I raised.

OK I was in J and am Gold but I think it was the specific and empirically
verifiable nature of my complaint and the fact that I alerted the Purser that triggered a structured and excellent response.
