We recently moved to 3119 Franklin Street Waterloo 50707. In the last week, we have had the following happen....a package was left on top of the mail box and tonight a box was jammed in; neither of these are acceptable. Our Saturday mail carrier does a wonderful job and will walk packages to our door and ring the door bell, even with a limp she walks the packages. Please inform the weekday carriers to bring our packages to our door, if they're too big for our standard sized mail box.


Hello, I am contacting you to request that the MAIL SORTING MACHINES be RETURNED to the POST OFFICE. Instead of sitting inside a garage. It makes sense that this machine can sort more mail FASTER than a person! Than our mail can be delivered faster. Now we have mail PILING UP. It is taking LONGER for my PRESCRIPTIONS and PACKAGES to get here! RETURN the MAIL SORTING MACHINES please! Thank You!


Does the Waterloo post office have an e-mail address where I can ask a question about a change of address?


some of our mail was found two blocks away that was post dated 6/11/20. We have different mail carriers every day and today 6/18 the mail is still not here and it is 4:05pm when we close at 4:30. We are a business and having our mail with checks and bills laying in someone's parking lot is unacceptable.


I have informed delivery and have not gotten my mail for two days. I called today but no one is answering the phones to tell me why. Our Mail carrier is working so why am I not getting my mail? I have two pieces that need attention this month that we’re to be delivered yesterday and today. You won’t, can’t get Covid 19 by answering the phones to explain why.


Do you not have anyone that answers the phone at your post offices???? What in the world is going on???????????


I tried to call you guys you put me on hold call me back in an hour and miss started at 8 o’clock this morning and I still have not received a phone call from you guys yet I like to know where my packages that can you call me at area code 319-215-9516 I’m getting really upset because it said that I was supposed to get my package today I put too much money in that package to get


If I put a change of address here for a person who doesn't live in Waterloo will it still go through?


Every time I send a package to this area it gets lost or stolen not only once but this has been happening for the last 2 years!


I am having problems with some of my mail getting delivered.! Both Century Link and TCM Bank have not received my payments since June and the checks have not gone through the bank either .So where did they go to when I know I have paid them


the passport service is slacking on answering phones, it'd be nice to get a representative to talk to.
