Today I flew J on BA056 JNB to LHR and a few issues with my seat/IFE, is it worth a complaint or should I just leave it?

Firstly, the footrest would only work at the 90 degree position, not the 'Z-position' listed in the seat guide. Even the CC said 'I don't think it goes any other way' and couldn't even see it in the guide! Which filled me with confidence!

Secondly, the seat controls were only partly functioning. I COULD get it to go fully flat and back to the seated position for landing. But there was certainly an issue meaning I couldn't get in the exact position for comfort! This was confirmed to also be an issue on the outbound flight by CC, who then forcefully told me 'they can do it manually if the controls don't work so it's not an issue!'

Finally the IFE screen initially worked fine, when it was extended it would stay where I put it. However, after maybe 6 hours it would not stay in place. I was advised by CC that they can give me a piece of paper to jam it in place! But I had already done this using my menu, but I do feel for the person who has if on the next flight!

Is it worth a complaint as if did detract from some elements of the experience, but I must say it didn't spoil the flight!
