My package, containing Prescription eyeglasses that I ordered from an online company never arrived in January, but were marked as delivered by the post office this company provided another pair of replacement eyeglasses which has not arrived at my home, although it’s marked as delivered AGAIN(!!!) In addition yesterday I walked the dog along the banks of snow on our quiet street I picked up a piece of mail on the wet asphalt, addressed to my neighbor I handed it over to my neighbor, who said this envelope contains a check!

Our mail is being thrown all over our porch and ground by someone, the situation is bad. If you could have someone come and check to find out who is doing this we would greatly appreciate it. We live at 810 2nd Place. Thanks.

Keyonna was very helpful. I came to the post office because I missed my certified letter that was delivered. She went out of her to make sure I got my letter. She displayed excellent customer service. I would like to thank her for going out of her way to help me.
