You have a postal worker/workers at the Dulles and Sterling opening and taking contains out of small packages that contain jewelry. This has happened to me twice in the last 6 months. Maybe security cameras of postal workers handling small envelopes would catch the thief at these facilities! If it’s happened to me, I’m sure it has happened to others.


The Dulles Post Office is a black hole that literally loses half of my packages. If a package is late or missing as soon as I see it stopped in Dulles I know- abandon hope all ye who enter here. Someone has been practicing their scanning on 92612909840841583092253008 all week without bothering to forward it to it's next stop.


PLEASE stop shuffling 9400109699939269422728 from merrfield to dulles and back to arizona....send it to warrenton where it is supposed to go. the address IS valid. I ought to know I've lived here for 20 years. Some boob mismarked it and now has been two weeks being sent back and forth with no attempt to deliver. SEND It to WARRENTON so they can deliver it!
