The carrier is not delivering our mail. My husband clipped tree by mailbox still she delivers our mail across the street to our neighbors. Yesterday no mail Im upset!!!!!


The San Xavier station is sadly about passing the buck instead of taking responsibility for the outright negligence of postal delivery personnel. After repeated requests not to leave items too large for the box laying out. That I will pu at the post office , My last item was severely damaged due to monsoon rains. Thrown in an area it's obvious that water runs with no plastic cover. Sad there' s no pride in their work.
