- JJJJ6 days ago5.0Mindi was very informative and so nice! She made my experience smooth and positive, which was lovely!
- AGAnthony GibneyMar 16, 20262.0Our new mail deliverer is terrible. We got a key to a lock box but it was at a different mailbox station across the street, only to receive some one else's package. Today, we had TWO very courteous neighbors deliver our misdelivered packages, and one of them asked me if I had theirs. Unfortunately the incorrect package I received was someone else's and not theirs. What a mess!
- WWWaywardMojoFeb 18, 20265.0Friendly staff and excellent service.
- CSChristina SchulzFeb 5, 20265.0⭐️⭐️⭐️⭐️⭐️ I had an outstanding experience with the Johnstown post office today. My package showed as delivered to a parcel locker, but no key was left. When I called, the representative I spoke with was incredibly kind, helpful, and supportive. He immediately contacted the carrier, ensured the issue was resolved, and I received my package the same day. What truly impressed me was that they even called me after hours to confirm I had received it. Their customer service absolutely made my day - thank you so much for going above and beyond!
