If I was the OP I'd probably be on here too, asking whether to send another missive to CR, or suggestion to who I might send in BA to get a response which actually acknowledges the issue I raised and whether it will be fixed /improved / lived with.

As a general observation, I do not think BA CR has (yet) evolved beyond the 'reply and dole out avios' level. At the very least I'd be wanting CR to have the skills to identify the genuine and helpful customer feedback and treat it as such.

We don't know much of the detail of the OPs seat and service issues, but I'm assuming the Seat broke in-flight, and OP couldn't be satisfactorily re-seated. Leaves me wondering (as with Henky) what generic issue is there that's wanting addressing?
