Customer Service?

I maintain a PO Box for an organization. I checked the box today and found a message note dated 10/20 that box payment is due by 10/31. There was also a note that boxholder privileges have been revoked due to non-payment, the 10-day grace period has expired. I usually check the box about once a month during slow times, and more often during busy times. I dutifully tried to make an online payment today. I set up an account, then tried to make a payment, it failed. I can't link my box to my account. The error message said to call my local post office. So, what do you think I did? Right, I called my post office. Want to know what they said? They told me that the PO Box department closes at 1:00 PM and I should call back tomorrow between 8:00 AM and 1:00 PM. The post office has been touting how easy they are to work with, and how they've been working to improve customer service - here's an example where they're a dismal failure.
