These morons are one of a kind. THEY decide on their own to return your mail to sender even though you have provided a valid address. It's just unbelievable the kind of headache I've been through to cleanup the mess these jokers made.


I requested to hold my mail while I'm out of town. At the end day of holding mail must be delivered. It did not happen. Most likely the delivery moron who does not know how to read dropped my mail somewhere else - this happened many times and looks like nothing you can do: THEY DON"T CARE, shame on them


The location is in the furthest possible corner of the map that could still be called Newbury Park. I hate when someone ships me something that requires a signature through the PO, I always end up having to drive over there. Used to be less than a mile from my home, in the middle of Newbury Park.


The service at this location is dreadful and the female who answered the phone re: my lost mail was beyond rude. I have no idea how people like herself stay employed when her behavior was not only unprofessional but downright unacceptable.


How much postage do I need on my official vote by mail ballot?
