The workers present at this post office should be FIRED ASAP, especially the mailman that delivers to MY house He has either a) delivered MY package to the INCORRECT address, or MISPLACES and LOSES them for MULTIPLE days on end Unacceptable how incompetent these workers are The USPS needs to hire a better group of workers to inhabit this building because the current ones are ABSOLUTE GARBAGE AT THEIR JOB


Very inefficient staff. I requested on the form to forward my mail temporarily for 3 months while I am out of country to my relative's forwarding address I provided on the form. It is Temporary. But the staff made their own assumptions and entered into their computer it as permanent move and send alerts to all mailers including insurances and my pension and social security to change my address because I moved out. It is a joke. I contacted the post office and they told to cancel the order they provided me. But again they changed my relative address and mail to my address because his last name is mine. He got such a headache. Who asked the post office to change my relative address? Can't deal with them anymore. Morons


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?
