    ⭐️⭐️⭐️⭐️⭐️ 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!

    Every staff member was very helpful and knowledgeable with my daughter”s complicated wedding invitations. Always a smile from everyone there and though it can be busy often, we are happy to wait because the staff is ways so nice.

    The new woman they hired does a lousy job, very slow does not know what she is doing. There should be 2 tellers working due to increased population growth instead workers are laughing in the shipping area while long lines of customers waiting to ship packages. Short staffed and poor management no one cares about the customer only profit. Very disappointed.
