Post 10 is good one. My guess is that either the check was lost and probably is no good anymore (usually company checks have a "cash by date". I'd go to the previous company and ask them if the check was cashed. If not ask them to re-issue a new check, cancelling the old one, and trying again. If the company did cash the check then they are in trouble. They have to account for every penny that comes in. I don't know who to call to get this straightened out. Best to you.
