'Why panic" most of us stand before you proud of yr actions here, well done & it has shown up what JetGo are really like despite their trying to back pedal now. It (email) might very well have been unsigned & sent from an unauthorized person but it had the desired effect & hit it's target with what would have been a devastating effect at first.
As I mentioned previously they have in a strange sort of way done you a favour here & maybe even some others who might be thinking of applying but will now think twice:-)
For all it's faults PPrune is a very powerful tool as is all social media in spreading the word, right or wrong!
We salute those that have morals
