    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!!!

    Martha in this office accepted a package after 1pm, she told me I was late, but I sent this package to Butte, Montana and the package still arrived on time on Saturday. And the carrier in Montana had to make a 2nd trip. He made the deadline for me. So I thank both of you. I appreciate so much more for one of our most basic needs. It is much easier if you are sincere in your actions. Thank you for that.
