You can never speak to anyone at the CAA nowadays, primarily because only a few know what they're doing (but your not meant to know that). Hopefully, having had time to contemplate their navel, the obvious will rise to the fore. Some years ago they had a department called the 'The bloody obvious and common sense department' staffed by people who knew their stuff and were willing to make decisions. Hopefully having had numerous meetings and having built up the courage to respond, you will get the decision that you want.
