Absolutely disgusting lazy delivery post persons. They cannot be bothered to use the sidewalk and they walk straight across our yard in front of the window. Despite numerous phone calls complaining about this practice it is still happening. By the way every time I call to speak to the Post Master she is conveniently out of the office.


I need to file a formal complaint. I have had enough...nothing but issues with our postal service. We dont receive our mail which has caused issues with bill paying, license plate renewal and now a large check that was never delivered to a service provider. I'm over $200 in fees because of the lack of service here. my neighbors consistently get my mail and I get other neighbors mail...like clockwork. I'm at a loss how someone can be this bad at their job.


Great Mailman Eric, He's Friendly and does a great job getting us our mail in a timely way. We miss him when he is off. Need more hard workers like Eric he knows his job and does it well.


After waiting on hold for at least 30 minutes (probably more) I got an impatient, slightly rude and hurried person who answered questions and was rather impolite and acted like she was more interested in getting off the phone than in helping me.


I am a very unhappy customer! My mail is often times not deliverd and when I go to this location to try and get help I get told I don't have a mail carrier and no one knows who has my streets mail. Its very concerning that I don't have anyone who even knows were my mail is. It never came today at all so did someone take it home? I was told to wait till after 5 and it would be delieverd by than and when it wasn't the office was than CLOSED so no one would help me. Iv now got over due bills because of this problem and no one will even help me.
