I ordered an item for my husband that I have not received. The company tracked it and told me it was delivered USPS Dec. 26. We did not get it. The company is re-sending. This is just another example of your poor service. Dianna was off only 2 days after her accident. She has still not gotten the red envelope left in our box for her for Christmas. You have a thief on your routes.


I understand that postal carriers are not required to pick up outgoing mail if the patron does not have incoming mail. So what happens when you have a LAZY MAIL CARRIER? You don't get your outgoing mail picked up EVERY SINGLE TIME you don't have incoming mail regardless if you have time sensitive bills going out that day. I have also witnessed a Fenton mail carrier THROW A PACKAGE onto my porch from the driveway WHILE SITTING IN THE DELIVERY TRUCK! The laziness of the Fenton postal drivers is pathetic.


This office is terrible, the people over the phone are rude, my mail person will someone not deliver my mail for 2 or 3 days and then deliver it all at once wroth a note saying my mailbox was blocked because there was a car parked within 15 feet of my mail box, not in front of it mind you but about 8 feet father down the road, God forbid he has to step out of his car to get it in my mail box.


Same here but not as bad with our newest driver I don't even have a car just sometimes people stop by and park in front of the driveway and Im not going to make someone move just to save them a few steps or pulling at an angle
