I tried for several minutes to talk with a Post Office employee in an effort to get an access code for Independence Mo. I stayed on the line for next available operator, and then the line was cut off. - Very disappointing,


As another email that I read, it seems that the number is always busy. My problem SHOULD NOT be a problem at all! I sent mail to Global Tel Link on 12/21/18 and as of 1/25/19, it had not been received. When I called them, I was told that the box number had changed and that I needed to wait until I got it back and resend!!! With a business like this, in my opinion, a box is NOT even necessary for delivery. I worked for the PO in my state for 18 years in rural areas where we delivered mail often times with the wrong address or no address! As the clerk here stated, the old and new numbers were not even that far apart and should have been put the right place even without a box number. I quickly mailed it after getting the money order so I am not sure if I even put a return address. GET YOUR CLERKS ON THE BALL WITH THEIR WORK!!!! This was negligence on their part and a big burden on me!


On Sunday a neighbor stopped by my house to bring me a package he found at midnight Saturday night lying on top of the mailbox stand in our neighborhood. This was merchandise I had ordered and been waiting for. It seems the mail carrier just laid it up there and forgot it when delivering mail to our boxes. This seems like really shoddy service and could have resulted in a financial loss to me. We live in Denver and our zip code is 80238. Would like a reply, please.


They steal mail after they process it to be shipped out of state. Most workers have no moral or pride but just steal citizens mail. I hope the thieves get caught and showed on the local new station soon.


USPS is doing a terrific job - that's in spite of the fact that CONGRESS has demanded that they put aside funds (for the next 20 years) NOW for pensions for employees. NO PAY AS YOU GO. It's a dirty trick that Congress has played on them. I live in a large condo complex and my USPS driver finishes delivering mail EVERY DAY by 6 p.m. or 7:30 p.m. That is the work overload employees are facing. Be thankful we have a reasonably priced mail & pkg delivery service.


I think they do a great job.
stop your whinning
My local people are nice and work hard


We all would love to have our mail,packages delivered when their supposed to be! Being both sides of the fence as a customer and also a delivery driver I understand that a number of factors come into play when mail is not on time,if you know what's going on with traffic,weather,construction and all the other obstacles a driver has to encounter to do the impossible,for the sometimes ungrateful,you wouldn't be so upset about getting your mail on time,but on the retail side of things,I agree! If your face to face with the public day in and day out,mail clerks should know what the hell their doing and should be more skilled in customer relations and problem solving ??

piss poor work attitude,send certified mail to wrong address ,when try to contact them about it they give you run around, very, very displeased. never had such rotten customer service in my life.


DO NOT TRUST YOUR MAIL GOING THROUGH DENVER! There is a problem with the Denver post offices and their sort facility. Damaged packages, tracking not up to date, bad attitude, email you with a phone number they do not answer, do not take responsibility for lost, stolen, damaged packages, late delivery, wet packages being delivered to door so that customers of merchants are left standing watching the delivery person's back as they walk away telling the customer to contact whomever sent package (their facilities must be in a deep lake or something to have water dripping off packages!), crap attitudes, send you around in a circle, thieves, and more. Very bad service and very bad attitude!
