I love the disclaimer that comments are not read by postal employees...that explains a lot.


Pretty bad when every single comment is a negative can't get service comment.


ANSWER YOUR PHONE!!!!!!!!! Ridiculous you are still a business, right?


There are 3 blue mail boxes outside my office building that are so full of mail its impossible to put anything else in. Its obvious the mail hasn't been picked up in days. I tried to call the office all day but no one ever picks up. Finally I called the main number and all they can do is take a report and have someone contact me in 48 hours. Horrible service!!!


I have the local office on speaker cell phone (just ringing and ringing) and the toll-free number on speaker on my work phone (just ringing and ringing). How frustrating.


Calling my local T.O. office and no one is answering. I have a very quick and simple question, but cannot get an answer 'cause no one is picking up the phone. Also my mail person keeps changing, which in itself is not a big deal, but they keep coming at different times of the day. No consistency! It's annoying. Got disconnected from my first attempt at calling. Waited a minute and called back and someone answered the phone.


no one answer phone what a joke, nowonder they are outsourcing the job.....


the mail person has been putting someone else's mail in my box and mine in other people's. this has happened twice.
