I bring packages to this location to be shipped and they aren't even scanned into the system for 2-3 days. No one will answer the local telephone number. It's hit or miss as to whether you get someone pleasant or someone awful while waiting in line.

This place is terrible, they don't deliver most of our mail ontime, and there are some days where they barely deliver at all.
