I pay $40 for a key that I can’t even get, it’s always something. We schedule a time for me to come and nobody’s there that can help? I’m absolutely sick of it. I NEED MY MAIL. I’m absolutely livid I have shit that needs paid.


I have had mail dropped repeatedly to our office that belongs to other companies on the same street. This has happen at least five times in the last six months. I have gotten mail that showed a Columbia MO zip code and one that was to go to Foristell, MO. I also have had a payroll packet that was sent to us never appear and I can only assume it was misdelivered as well since it was sent from St Peters to Truesdale Nov. 18, 2019 and is still has never appeared.
