Packages missing ...packages continuously delivered to driveway not even close to front door ..had addressed this last year was good for awhile .spike with “ postmaster who did not give name ..I had to ask


In the past year, the service has gone downhill at the desk. Packages take forever for us to receive even though we know they have arrived because we get a confirmation email. We realize it may take a day to sort through, but we don't get anything for days. Then there's getting yellow slips in our PO box and the people at the front desk telling us there is nothing there and the next day, there's 5 packages. Also, we have gotten other people's mail more times than I would like to admit. We always have them the benefit of the doubt, but this past summer,mid-August at about 9:30, I went to the desk to retrieve a package and an older man with glasses was helping a customer and there were 3 people waiting and after about 10 minutes of waiting we asked the man if there was someone else working and he just ignored us. The lady he was helping even said is there someone that can help these customers and he replied, "I am helping you." At the same time we heard many voices in the back talking about boats, cars and other personal things. He never looked up and acknowledged us. We waited another 10 minutes before someone in the back came out to help and then heard another loud guy in the back say, "what the customers don't like hearing my big mouth?". This was just one time with this man, but there were many others with the same scene and there were a few instances where a tall woman with glasses and short hair was working and did the same thing and was VERY slow. I chalked it up with maybe she was new, but it's been the last year and we have been using the post office for 20 years because we have a PO box there. The lack of help is disturbing and I get the sense that the clerks get annoyed when they have to help someone which is there job!


Awful awful awful post office. Late bills all the time bc I never get them. I don't get much of my mail at all. They speed by so fast and is always in a rush! Didn't get a package once either. What a surprise. How do they get away with this


Worst post office ever, multiple times was told delivery attempt was made but package could not be left, every time there was someone home. Time stamp of messages not even normal delivery time. When tried to complain about it, started getting mail delivered late. If it wasn't for text reminders I would of had to palate fees for bills that showed up days after payment due. Amazing how they get away with it.


Terrible post office, packages get delivered to the wrong address all the time . Mail carrier bend mail clearly marked DO NOT BEND. Post master seems completely clueless when asked about these problems.
