If you know the name of the company that owes you the money, I would look on their website for any other phone numbers that might at least get you to someone in the building. Then maybe be able to be transferred to the person that you need to talk with.
So you guys used to be part of the show over by the Casad depot? I’ve been a few times, great show.
Unfortunately I can’t make it this year, Boy Scout Camporee in Kendaltucky that weekend.
Does your group go down to the show in Portland? I’ve never been to that one, always wanted to though.
