I don't understand what is wrong with the person delivering our mail, He keep mixed the mail with other neighborhoods, I talk to him he say sorry but still do it 3 times I went to the office a couple times they very helpful and addressing the situation but this keep happening, last time was last Friday 10/9/2020, I follow him and give the wrong mail back, so he can put in the right mail, well he not, he just trow the letter in the box and leave our of the subdivision, now I'm more worried about my mail delivering complete.


The mail lady keeps leaving the wrong mail in the wrong box today I was expecting welding supplies over 50dollars worth and got someone free baby formula And this is not the first time she has done this this is like the 6th time wrong keys in box and million time wrong mail I live on coverview and get vegas dr


Our packages are not delivered to our address, that's something we have lived with for the last 8 years out of the 23 years we have lived here. NOW there is never a slip left in our mailbox! Our packages sit for weeks before we are able to track them down!


So they couldn't deliver my package and instead left there little slip which clearly states that should I need someone else to pick it up to sign and put that person's name in. My rep gets there and is told they cannot pick it up because they don't have a photo copy of my ID. Then when I call to speak with the postmaster theylaugh like itsabig joke. I will be filing a formal complaint.


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.
