I submitted a change of address form in June of 2019. When I went to check my mail at the postal store where I have my PO box in September, my mail was still not forwarded, where is my mail????


Tried to call 2 hour wait every time my carrier is off we don’t get mail this is ridiculous that’s why I try not to use post office for my parcels


Listed PO telephone number goes to a fax line.


Hello ,On 6/12/18 the postal man drove his truck down my driveway and over the grass damaging it.Please tell the carrier not to drive down the driveway again.I called several times and no answer. !4 Fleetwood drive Danbury ct 06810 . Thank You


I have been trying to reach the office with no answer and then goes to a fax like sound. The 800 number gives me a 2 hr wait time. I was supposed to have a package delivered yesterday 2/11 and it never came another package was delivered on 2/11 and got a message that this package couldn't be delivered because they didn't have access. I live in a house no access required and was home. It is a small package. If 1 package could be delivered why not the other. I can't get any info on this and it is not saying that it is in today informed delivery. I'm very upset with the handling of this delivery. Don't tell me 1 package could be delivered and no access for the other. Would be great if one could speak to a live person!!!


I have called many times this morning, July 25, 2017, from 9:00 until 10:35 AM and no one answers the phone. What is going on there?
