The Mailbox Cluster needs to be repair .


there is more lying going on at this station.i had at least four or five parcels to be delivered, but no one came by. if my mail is in the station, why didn't someone leave a mail box stayed empty all day so I know no carrier was here.why have these reviews if you are not going to do anything about the?


I was notified by my neighbor that he had observed the mail carrier leaving mail outside on ground again. He has informed me that he has pictures and he has picked up mail from the yard where it has blown off the porch from the wind or put it in the slot when it was raining. (There is a mail slot for it to go inside.) When I arrived today he was angry and stopped me again. Both my and my neighbor’s mail were wet from rain and laying on the ground with a rubber band around it. We sometimes get each other’s mail and we neighborly walk it to each other’s slot. Not sure why this is happening but would like to have it addressed.


This location needs more tellers it takes up to 20 mins most visits to get to the window and be serviced. I've lived in this area for 3 years and nothing has changed.
