I'm not entirely clear what the point of all the bickering is, really. And frankly, the evidence posted really doesn't provide much substance, between the lines or not. I'd recommend posting a screenshot of the page with any identifying ID numbers, account information, the like, redacted. I'd PM but apparently I can't without writing 5 useful messages (which I think is a subtle code word for "flames").
Also, did you contact FLC after you got stiffed? How did they respond?
