Sorry to hear that you have been taken for a ride.
In your message you mention that, "they, the airline , making big money.
What makes you so sure of that. Maybe they want to get cheap labor to cut costs wherever possible?
There are rumors floating around that all is not well with them and maybe your untimely departure was a blessing in disguise?
But the way they have treated you is indeed uncalled for. When did they terminate you? Where did they send you for the typerating?
Anyway, good luck, you will need it, don't give up.
regards
