Nobody answers phone.. the other phone number. Is a deadend loop referring you back to web. I want to rent a p.o. box but i cant find any info.


I was left a " sorry i missed you " notice from the Nampa post office, which stated that postage was due to the amount of $1560. 2 packages from amazon each costing $780. I tried to call the Nampa post office, but no one will answer the phone. I finally called the main USPS number and talked to the fraud department who transferred me to the supervisor at the Nampa office who informed me that the amount was supposed to be $15.60, there was no decimal point on the form. Then i asked him why no one answers the phone over there, this is where is started to get defensive, stating they answer the phone all day, i told him i have been on hold for 25 minutes there this time,i hung up after a long period of time last time, because someone did not even answer the phone, but just put me on hold. He did not apologize he continued to sound defensive. This is terrible customer service! There is comment after comment on here about no one answering the phone there. I guess if you want Nampa post office to answer the phone, you call the main number for USPS and talk to the fraud department and they will transfer you to the supervisor. I suppose this is one of those government jobs that you can get away with being rude to the customer.


When the mail lady delivers a large envelope that says "do not bend", guess what she does. Folds it in half and shoves it in my mailbox. She did this to my college diploma 3 years ago and now she did it yesterday to a certificate. They are both items id rather not have all jacked up. Thanks a bunch USPS.


When are you going to deliver to the Willow Creek sub-division? Haven't seen a carrier in a week...What are you doing with the undelivered mail????


Too bad they can't afford a working telephone. If the telephones do work then it is too bad they don't have anybody that knows how to answer them...


I have found the same thing to be true. I've been calling all morning and no one is answering the phone.

Going on three days without mail delivery service. Calling all day and no one will answer Nampa PO. Very upset!


Anything sent to me gets returned to sender. Any packages with tracking, state that it was returned due to my home being vacant. I think the mail deliverer is too damn lazy to do their job. Fed up!


Nampa Post office SUCKS... they NEVER answer the phone... EVER. Tried at least 2 dozen times over the last week....typical lazy-ass government employees.


It is October 24, 2015 and it is 5:46 pm and our mail just got delivered. I guess she is trying to beat her 8 pm delivery time.


I am just wondering how our mail carrier gets away with delivering the mail up till 8 pm at night? I live in the Happy Valley Trailer Park. Is it because she takes 2 hours lunches or she runs personal errands? Have seen her do both. Not wanting to get her fired, just want her to do her job.
