Such a crap service in my area. They open after my work start time close before I get off and are closed for 2 hours!! in the middle of the small open hours.... Then if a package is bigger than a letter, who knows if you'll get it delivered or not. Sometimes they'll send a 2nd vehicle past your house to bring it or maybe they will just mark it as 'Delivery Attempted' and say "Nah, I know we were paid for shipping this and are driving to your house anyway but you need to come get it because we don't want to lift it..."


I have been trying to contact Dittmer post office regarding a package that post office said delivered on 7-10-20 at 1:55 pm. I was home all day on Friday and no package was delivered.
