Had a pkg returned to vendor over 5 weeks ago. Post office website stopped tracking pkg and lost its location. Trying to get help from post office staff 3 weeks now. Post master has no interest in assisting and literally closed his door in my face. I should never had trusted these people and the organization. Now I'm out the value of the pkg since I cannot get proof of delivery. If I could give them a zero rating I would.

Worst post office it possibly can is the current state… , which was a couple of years ago the best. What a negative transition. Majority of the front desk post office workers are latterly found sleeping at working hours and the postmaster doesn't care. Shame on USPS to hire such new irresponsible workers…a waste on taxpayers dollars

Horrible place!!!! Don’t ever go to this place I asked for a pen since none of their pens work and the lady said that they don’t have it . She wasn’t wearing a mask and we had to ring the bell like 4 times because she went going to the back all the time .
