Worst service ever and i got my knee mangled. In parking lot and the postal employees only worries wore the next package


I hate this post office. They have a high frequency of delivering packages to the wrong location. Yesterday they marked my wife's birthday present as delivered and yet there was nothing at our house. F*ck them.


is the self service machine fixed yet?


They never actually deliver anything. If it doesn’t fit in the mail box they refuse to walk it to the door. I am home all day and they keep leaving notices in my box saying they tried to deliver my package that didn’t even need a signature when they obviously did not. I had to go pick it up and the girl even laughed and said they never deliever anything, she said they never even put it on the truck.
