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...


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.
