Mail tampering @ 1500 Boston Post Rd


I live on 12 Shetucket Trail. We would like to move our mailbox to a different location in our parking lot. Does this require approval?


I get the pictures of my mail at 7:20am before the mail arrives between 10:45-11:15..Friday I received an image, the envelope was not in my mail. I waited. Monday I was to get more information from the same source, I waited for the mailman. No, that piece wasn't either but everything else has been. ???


My tracking info. Says you attempted delivery
of a package to my home at 2:17 on May 3 . That is incorrect as I was home and actually in my driveway at that time, doing chores.
Please contact [number removed] to explain. Package can be delivered Monday, TO my FRONT DOOR! I will be here. DO NOT GO TO MAILBOX AT END OF DRIVEWAY. CALL ME TO EXPLAIN THIS AS NOONE CAME TODAY. HOW CAN YOU SAY YOU WERE HERE WHEN YOU WERE NOT!!!! ????Nancy Nicholas
