I really have no words for the multiple times I have not received some of my mail. I signed up for Informed Delivery to track mailed items I am supposed to receive. It's a waste of time filing a complaint because the issue isn't resolved. I am also receiving someone else's mail that I return to the post office. It is become too frequent with me not receiving my mail not to mention important mail. I am very frustrated and fed up.


I was told I received my package May 2nd at 3:04pm. I get my mail everyday. I never received it. PayPal credit told me.


My mail carrier has no concern for the integrity of the package he or she is delivering. I ordered clothes for my son and the carrier forced the package to fit inside my mailbox and it ripped open in the process of pulling it out damaging the products inside. Of course, the number listed here isn't a valid phone number for this post office.


Is there a mail carrier for 35th,and Harrison St
