Or why not write to the CAA with polite and constructive comments of precisely what your problem is.
I frequently read rants and missives, both here and in the G/A Mag's about how dreadful the CAA are, yet it's very rare you ever see a constructive critisism.
I'm not defending the CAA, but if you can't adopt a more mature approach, no one will listen.
Professionally, I am governed by and have to work alongside the CAA (Safety Regulation Group and others), and if I have a problem or a grievence, I find out who it is appropriate to contact and speak to them.
Instead of bitching and being deliberately antagonistic, why not do the same?
I think you'll find that if you tackle your MP in the same way as you post, they'll make the same suggestion as me and tell you to come back equipped with the direct evidence that the CAA are not doing their job properly.
