This is not a problem about the mail carrier they've been wonderful. But over the last 3 days we have gotten no legitimate mail except for promotional advertising. As a physician I'm used to getting journals and several pieces of mail from my organization etc. this is very strange that nothing has been received and I would appreciate if you don't look into this. Thank you Nancy Solomon M.D.

Almost every comment/problem already mentioned has happened to me. Mail delivered to my neighbors, or strangers. Notes left at my door saying they were sorry they missed me, while I stayed at home waiting for the pkg. to come, and the doorbell or knock never came. Terminal busy signal when calling the office. I even followed the tracking on a package sent to me, and it said it was handed to the resident. Definitely wasn't handed to me. Seem to have a different mail carrier every few weeks. I have issued complaints that go unanswered. I now go out of my way to avoid using the Post Office altogether. What once was a cherished and friendly entity, is now an act of futility to get mail.

This is the worst Post Office employees are rude. They deliver our mail top the wrong address all the time. Neighbors get our mail. They lost a package and claim it was delivered then claimed they had no idea what postal person delivered it. Basically the supervisor said too bad on not receiving the package, too bad your out money.

Bad experience with the supervisor when I complained about my mail not reaching the recipient in time. She was rude, unapologetic. It would have been ok with me if she admitted that "I don't know the answer & let me try to find out for you". I let that instance go but today I got a return to sender birthday card I mailed October 25th, certified & the post office delivery woman today handed me the card. Same attitude as the supervisor, unapologetic. I am done with this post office & moving somewhere were in the employees esp the management will do their job & treat the customers better. How come they choose people in the management who are unfit to do the job? On the positive side, the ones on the counter are mostly respectful, nice.

I have filled out 3 forms at the post office over 4 months to change my address from the house to the P O Box permanently since we have had mail stolen. 3 times!!! Now I get to stand in line to pick up my packages IF they can even find them. Today I find a note in the mailbox that I have to go onto usps.com to "forward your mails". Go online to do this to find that they need my cc# and will charge me $1.05. Are you kidding me?!?!? According to the bottom of this website it isn't even run by the USPS. Wish I could avoid USPS altogether!

Cost me a penalty on my taxes (more than $1000) because I went to the post office and the last collection time from this website was incorrect. It stated 5:30. I showed up at 5:05 and their last pickup was 5:00. This website looks like it belongs to the USPS, but it is not. It is not. VERY VERY MAD.

I had to get a package today and all I got was a paper on my door saying that they had sorry we miss you today and I was here at that hour that they came. Now I have to wait 3 day get get my package from the post office

HORRIBLE SERVICE!! Susan Gouda (couldn't understand her muttering) put me on hold when I called, I left my house after 5 min.s and drove there, got to the counter, and told the representative that I had been on hold for 14 mins now, and sure enough Susan, the one who answered the phone and put me on hold was standing by the front of the line, picking her nails… When I approached her with my issue, she basically told me too bad, call the Postal Inspector. I asked for the phone number and she told me to look it up online. No wonder why everyone is switching to UPS, FedEx, and the other delivery services. Due to people like Susan, the post office will eventually lose business and continue the furlough days. TO ALL ANGRY POST OFFICE EMPLOYEES: Thank Susan for your furloughs, not to budget cuts, but loss of business from her...
