2/4 packages expected today NOT DELIVERED. No one picks up the phone. Automated line entirely useless. They have lost or misplaced or simply not delivered 4 of my packages in 3 weeks.


These people do not seem to think they have a job to do. The phone is not answered unless someone calls 8x+ in a row. I was transferred to speak to a manager 50 minutes ago and the phone is still ringing. It is 9:17am now and the post office was just open when the call first started. Aren't these people accountable to ANYONE? What agency provides oversight?
