We have never had such bad delivery service in our life. We sent a check to my Grandson three weeks ago he has still never received it. We sent Comcast our monthly charge of which they never received and now we received a double bill plus penalties. It looks like we will be forced to pay our bills on line. I am told by our mail lady that your sorting of mail is not being done on a regular basis. I am extremely disappointed in the US Postal service.

Not only is the wrong mailed delivered to our home and our neighbors regularly on Dauncy road. And, isn't it crazy that any post box still left has been moved to a location that requires you to get out of your car to deposit the mail to it. Seems no one thought about people who are handicap and it isn't easy for them to get in and out of a vehicle...Plus they did not consider excluding a parking spot near the box as a NO PARKING spot only mail drop off. Who is the brains behind these decisions!!!

POOOOOOOOOOR We get mail for other neighbors at least once a week and on Jan 22 we put a STOP MAIL card in our mail box to start on Sat Jan 24 and restart on Feb 7. Well you people are so reliable our mail was never stopped and was just delivered to us by a neighbor who discovered it was still being delivered. What do you people do for your pay check?

THE MAILMAN OR WOMAN OF THIS POST OFFICE IS HORRIBLE AND LAZY!!!!!. MAIL CONSTANTLY DELIVERED TO THE WRONG ADDRESS AND WHILE RESIDENTS ARE HOME PACKAGES THAT ARE DELIVERED ARE JUST LEFT AT GARAGE DOOR FOR SOMEONE TO TAKE. LUCKILY IT WAS STILL THERE WHEN I LEFT FOR WORK THE FOLLOWING DAY. THIS IS UNACCEPTABLE SOMETHING NEEDS TO BE DONE!!!!!

So so so Tired of this post office, Constantly having wrong mailed delivered. Who knows how much of my mail goes missing. Like Mr. Burton second time not receiving my Water Bill, but at least the late notices arrive, before they shut off the water. I don't know what needs to be done, but completely unacceptable, and this will probably fall on deaf ears.
