Hello! My Shipment - CI001297660NL is at your center-USPS Regional Destination Facility LOUISVILLE KY DISTRIBUTION CENTER , please tell me when to expect it to be delivered to me? Thank you for your time! Be healthy!


We did not have mail service today. I called at 4 pm and was told they were running late but assured me they would come. I had a check in my outgoing mail. I left home for church at 4:30pm. When I returned at 9pm, the letter was still in the box. I tried to call about it and kept getting recordings that they were closed. Tomorrow being Sunday, I am afraid nothing will be done. We are 80 and 81 yrs old. We try to do things the way they should be done. We expect others to follow through when there is a job to be done. My phone is 241-4421.


Hello My name is Christian Graham, I work for the Louisville bats and we have not received our mail for the past two days. We wanted to know what was the issue? Thanks
