"WP" I feel for you & fortunately most here are sympathetic to yr plight, shame about the few who think somewhat oddly but I guess we are all entitled to an opinion right or wrong.
I hope you can get some legal advice to yr benefit & turn the big stick around & whack them over the head!
In a strange sort of way JetGo have done you a favour by saying such school yard bully crap as it shows their mentality already to treating pilots & you don't even work for them!
I note "PB" is listed as the MD, interesting, haven't heard that name in many years.
