Atrocious. I wouldn't bother with the comments card, I'd write to WW's office direct, copying Mr. Tallin-Smith as suggested above. And if anyone can tell you who's responsible for inflight safety them too.

The dire crew attitude and service is one thing on its own worthy of a complaint - the safety issue of not securing the cabin properly another kettle of fish entirely.

Thank God I have never had a crew like this. I hope I never do either!

If you write it as factually, dispassionately and in as much detail as your original post ^, I sincerely hope they take a lot of notice very quickly.

Edit: and good on you for talking to the Captain too. If you do write in and the Purser claims you are exaggerating, BA do have teams which can contact other pax on the flight to verify your version of events - I would imagine 100 or so people can back you up by the sound of it!
