For the Brits............
For the Brits, it is very simple. Complain to the CC, and ask for a copy of the record that they have made. If they have not made a record, ask for a signed document to that effect.
Then, take the offending sandwich to both elfinsafety and to trading standards. Put all comms in writing, and if sending them via the post, send only via recorded delivery.
Take/send all the paperwork to both the CAA (SRG, lgw, FOI group - complain about the poisonning of pilots) and the Daily Mail.
