unmonitored shared box?

at work i had a question from a colleague about a check file that i print. i said it was low volume, few and far between. just seven checks for the month, just over 40 for the year. something about a caller had questions on a payment. the file has a return address in Memphis, although the only contact we have is a shared box and no one responded when i sent a message there. i got a 'thumbs up' when i spoke of it. one clue from a check that was returned said forwarding time expired and seemed to say the business line moved to the suburbs of Kansas City. but it doesn't seem like a high enough priority to pursue further. i saw a text message and i was asked to confirm a dental appointment, in a week from now. two payroll checks were picked up, in the morning. i said 'you win a cookie' to the tax specialist, in reference to the movie 'Kelly's heroes'- about being the first visitor of the day to pick up checks.
