Congratulations on your NPPL.
Complain to your MP.
Complain to whoever leads the Red Tape Challenge.
Complain to the LAA.
Complain to the NPPL steering group.
If it makes you happy. Complain.
If you want anything done, forget it.
If you want a reaction, use fruity anglo-saxon language when talking to the CAA and they will try and prosecute you for assault! (at least so implies their telephone message)
