Didn't you get a preemployment letter??

Wait, so none of this was set in stone? Job offers and home options aren't exactly guarantees, they're possibilities. And scams, apparently. I'd like to know why you moved before everything was established. One of you/your partner could have gone ahead, and made sure it was all sorted, your jobs were secured, your home available, and then it would have been okay for everyone else to move, as well.
