I receive mail from another household ALL THE TIME. (we have the same house number, not the same street or the same community) I am continually returning it to this post office and they don't fix the issue. I have put the flag up for them to pick the items up and they leave it in the box. I even call and speak to the post master and tell her the mail is still in the box….its still there 3 days after I talk to her! For months we had issues with the mail person leaving our packages at the neighbors house rather then bring them to our house. Its just one thing after another, but the delivery of someone elses mail, including their medications, to our house repeatedly is just unacceptable! There is no talking to anyone down there. They will tell you they will fix the problem and do NOTHING. The message below says that they got a notice a package was delivered and it wasn't, trust me, we have had that happen MORE THEN ONCE and the package never showed up---guess its at the other house since their mail is here!


I received a message that my package was delivered to my porch at 7 1st ST, Lothian, MD. I did not receive this package. The tracking number is 9361289678090084734422.
