There is no such thing as "EU 261 HQ". The national enforcement bodies do not get involved. If you need assistance, you would either require the services of one of the specialised claims agents (and the person upthread that reports no success having used one after 19 months is probably going to end up disappointed - they do not pursue everything to the bitter end, and if they've not managed to get money after this long then it is looking unlikely they will be successful), or bring a case in the (small claims) courts.
And I would advise against lumping two separate, unrelated claims in the one letter. Better to tackle the broken seat compensation first - and then, once that is resolved, move onto the EC261/2004 issue.
