for some reason some of my mail is not gtting delivered to my address. my rent check was sent back and target called me yesterday and feb/march/april statement was sent back..i went to upland PO. talked to a supervisor..he was the super for the front/he doesnt no how to do the back.i was told the super was out in the field checking on the mail people. i have not changed my address, the super told me i would get a phone call today..well that didnt happen. and by looking at this so called supervisor..he looked like he just walked in from the streets. he had no uniform on. still waiting...i hope i dont have to go back down there. and i hope im getting most of my mail...i get the junk mail..lol. but i pay my bills..i had 2 late charges from target...this has to stop.


HORRIBLE. Stolen 3 items. I would say lost, but ALL three were never scanned. BAD BAD BAD business. Got basic shrug of shoulders in response.


Today March 12, 2015 tried to get in touch with the Post Office just to let them know our mail was not delivered on March 11 was on hold for over 5 minutes and then hung up in frustration. Seems funny to me that on Saturdays our mail is in the box before noon and every other week day it comes close to 5 PM.We had a wonderful person delivering our mail around the holidays and they took this man off our route, not sure why. Since then we have noticed that there have been several days that we have not gotten mail and these are days that you normally get junk/ads. Something is wrong at the Upland Post Office.


Omg!!! This postal office is horrific, I've mailed out bday cards thru this office within the past 2yrs and I have the correct infor/address on the cards as well as the return address, for the 3rd time, the cards never reached their destination and the gift cards that are only $25 to $40, never were returned to my home address. I truly think there is an inside theft problem ... Please do not send gift cards thru this postal office. I didn't think I wud have to get Insurance on a Bday card, but this is crazy... I've filed a missing maill form, but it's been 2wks and they have not replied..


I live in Paso Robles, CA. Five days ago, I sent a package to my friend in Upland, in a FLAT RATE box paying $11.65. The post office tried to deliver it to her today, and said she owed an additional $6.60 for the box. She refused saying that it was in a flat rate box. IF the box comes back to Paso Robles, I will take it to the Paso Post OFfice, and explain the situation to them. A FLAT RATE box is just that...flat rate. It was in a priority mailing box...2 day service, but it was not delivered for 5 days. No wonder the post office is loosing money, and customers.


Is it legal for a husband to open a wife's Disability Mail? We are living separately.
