- WSWade SempleJul 6, 20253.0It said my package was to big for the mail box so that said they have it back at USPS .. I always get deliveries from USPS and every time , and every time they have delivered it and put it on my stairs.. I'm disabled and can't get to the USPS
- HWHannah WyethDec 3, 20221.0Horrible office, horrible staff. I moved here a year ago and have nothing but issue after issue. Mailman refuses to get out of his truck to deliver packages. And when I go to pick them up, they oftentimes "get lost". I get alot of plants and I swear he purposfully won't deliver them and holds them over the weekend to try and kill them. I look at tracking status and it says "held at office by customer request"! THEN THEY ARE RUDE WHEN I DEIGN TO ASK WHY IT WASNT DELIVERED ON TIME! EFF this whole post office. I'm surprised someone hasn't written to the attorney General yet. Lord knows I have come really close.L not to mention the amount of money I have spent replacing broken packages b.c he threw them around or clearly stuffed them into the mailbox they didn't fit in so he didn't have to get out of his truck... smh
- JMJ MckeeNov 28, 20213.0For us working people we need the post office open longer on weekends . It's crazy that po boxes aren't 24/7 either..
