Service is spotty at best. There are days when we do not receive any delivery. This is not because there was no mail to deliver. Of that I am 100 percent certain. As a business owner, we depend on daily service.

This post office does not answer the phone . They let it ring then disconnect the connection. The postman seem to deliver mail when they choose too. Great job if you can get it. This week we have not gotten mail Monday or Tuesday. Talk about a golden parachute.
