I am continually disappointed in the delivery service from the Marion, NY location, and especially so since its relocation from the Williamson Office. We have received portions of our neighbor’s mail on several occasions in the last few months, the delivery time has been consistently after 3pm (easily 4-5 hours later than it has been for the 11 years we have lived here). The latest frustration occurred when a package that was tracked as delivered to the Marion office on Friday, never arrived in our mailbox until Monday afternoon at 4pm! I needed that package for the weekend.
