Yes, this guy must be trolling, but for the benefit of anyone who might be taking this seriously, here is the pivotal fact:
I paid line training with them
Read it again. 'I paid line [for] line training'. Got that - paid for
line training. You got your line training and now the deal's over. Finished. Over. Complete. In accordance with whatever crappy little paid for line training contract you signed. What were you expecting, a bunch of flowers? (I know the answer - you were expecting an employment contract to appear out of nowhere.)
Speculative pay to train schemes are suicidal.
Don't pay for a type rating unless you have a rock solid job at the end of it.
Don't pay for line training at all.
Simples.
