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.
