Uncomfortable "Premium Comfort" seats and rude staff

I am a member of Flying Blue and have flown AF several times. This was the worst flight yet. Firstly, the seats in Premium Economy (or Premium Comfort....) were uncomfortable and did not recline at all. Or if they did I didn't work out how to do it - no one else seemed to either. Secondly, they seemed to ration the water. We did receive one 500 ml bottle on boarding but for an 11 hour flight that doesn't last long. Any more water was rationed in tiny paper cups - two sips and it was finished. I was severely dehydrated and eventually went to the back of the plane to beg for water. Admittedly the seat belt sign was on because of mild turbulence but no crew were offering water or anything else. The signs had been on for over an hour before I went on a search for water. I was shouted at for being out of my seat and given the rationed two sips of water. When I asked if they had any bottles of water I was rudely told "No, we don't have any bottles" - not politely or apologetically, but angrily. (I might mention that I speak French, so it wasn't because I was speaking English). Having paid double the price for Premium I was not impressed. An hour later the seat belt sign was still on so I called a crew member. It took them over 15 minutes to respond after which I was given a paper cup with two sips of water in it. I cannot recommend Air France Premium and will look for a different route next time.
