Twice in the last three weeks I have placed a note in my mailbox (flag up) to have the postman pick up a Priority Mail package off my front porch and he/she did not pick it up. I paid for Priority Mail shipping and did all of the correct things on line but you cannot schedule a pickup for the same day if it is done on line after midnight. Why is the package not being picked up????? I have done the same thing probably 25 times before and the carrier ALWAYS picked up the package if my note was left in the mailbox. Can the new carrier not read????


Why is your lobby closed at 5:00 am when your website says lobby hours open at 4:00 am????? Very unprofessional! Lobby Hours Mon-Fri 4:00am - 5:00pm Sat 4:00am - 4:00pm Sun Closed


I bought an electronics item. It was shipped on 4/24/17, priority mail 2-day. The package was scheduled to be delivered om 4/26/17 and required a signature. My mail usually arrives between 11:30-12:30 everyday so I stayed home and waited. At 1:00 still nothing so I cut my front lawn. I never left the front of the house for an hour. Nothing. Later I checked for any stickers on my door saying a delivery was attempted. No sticker. I tracked the package and it said delivery was attempted at 1:36pm. IT WAS NOT!


I have mail that hasn't came yet love Mrs. Mr. bulanek.
