Sometimes they will offer you a very small percent of what they owe you. Most of them cheat, and if they are Isreali run, then they cheat for sure. Keep at them, but if don't expect to get the full amount, they will probably offer you something like 20% of what they actually owe you, and call it a gesture of good will because they are good and honest blah blah BS. It really depends on what reason they are giving not to pay you. Do you know where they are based? I know a lot of them, and may be able to give you an idea of your chances, if I know the ones you were with.
