Every other day someone's mail in my Apt Building is placed in the wrong mailbox. Keys for the 'large item boxes' are put into the wrong mailboxes causing loss / theft of high cost items. On 05/08/17 I found my BANK Statement pinned to the cork board above the mailboxes, yet another piece of my mail misdelivered! My mail goes in the wrong box 2-4 times a month! This must be corrected ASAP!


Somebody from U.S.P.S.left a package last monday, 9361289674090207708679, on a ledge in the foyer, with the locked mail boxes. Jarrett, one of the reps for the Villaggio, said he saw a package just sitting there when he was showing the apartments. Obviously, I did not get it. What kind of idiot would just leave a package in the open area! Usually, if the package is too big for the little mailboxes, they are left in the office. There were some sensitive things in the package. I would appreciate an answer to this as a tax paying U.S. citizen Robert Kelsey


Wow! These guys never fail to disappoint!


Amazingly bad service at the Kirkland PO.
