I don't mean to be rude, but, perhaps your friend should have delivered the letter a bit earlier? Especially if it was something of importance, I would have thought two weeks was cutting it a bit fine? I assume that if there was a set date for the event, it was known a bit further in advance?
And the same as your letter, I guess from the dates that you wrote to them three weeks before needing the advice? Again, in my experience with them, a bit more notice might have been needed?
Not that I'm defending CAA for one moment, but ...
