We have been in this home almost 3 years and have had a constant issue with not receiving our mail. We receive mail about once or twice a week and alot of mail isn't ours. And we live on center Avenue the same road as the post office


Very poor service!! Too lazy to deliver packages to your door,then you have to go into the office to pick it up where the rude poor service continues!


Yup ours is left open as well at times. Today was expecting a package only to learn fed ex took to post office this morning. Tracking said pkg was left this afternoon. NO PACKAGE. AFTER ABPERIOD OF TIME TRYING TO FIND IT. I LEARNED IT WAS PUT BY THE MAIL BOX. BY THE ROAD. COME ON. I WAS HOME DURING 3:37 pm delivery. And you couldn’t get out of your truck and put it on our porch? Ok left house at 5:09 and there was no omg by mail box. IN THIS DAY AND AGE. PUTTING IT BY THE ROAD IS OK WITH YOU. WHY DONTVHOU JUST STAND ON THE STREET AND GIVE PEOPLES PKG’s AWAY. 🙄😡


Poor service at this location, when I call them about issues they are rude. I get mail delivered to my house that is not mine. I have not received important mail that is supposed to be delivered to me at times, and after several attempts to call and ask politely that the mail carrier close my mail box door after the mail is delivered my mailbox door is wide open at times yet. How hard is it to close mail box door?


Same complaints I’ve had for years!
