    Worst hours of a post office I’ve ever had. Not open on Saturday closes at 4pm on weekdays. What a joke. And they also sent back a package I ordered to the sender for no reason.

    I experienced a few issues with Package deliveries. I went to the Greenfield Post Office to share my concerns. I was greeted by Melissa at the front desk area. She was absolutely amazing and made me feel like the issue would be addressed and corrected. The problem was corrected and I am very happy with the outcome. It was so nice to receive excellent customer service. Thank you!!!
