Having a problem with our mail Not being picked up at 2813 Ridge Ave. Sioux City, IA. This has happened several times and I am getting upset. They walk by and don’t bother to look up to see if we have outgoing mail. Thank You

My mail man was scared of my 5 pound dog and pepper sprayed her. I had to sign an agreement that I would have my dog inside at that time in order to get my mail. I have not received my mail since. I have to go pick it up. My son ordered some parts for his skateboard. We just received a notification that his package is being returned to sender because it can’t be delivered. The government finds every kind of way to screw people over.

I don't receive a good portion of our mail, I have to deliver mail a few times a week to neighbors. I Have sent letters to myself from other locations and never received. I can't get medical care I need because I haven't received insurance cards that have been resent 3 times in the last 2 months. I hope something can be done.

Didn't get mail delivery on Saturday, 1/18/2020 or Tuesday, 1/21/2020. Will there be mail delivery on Wednesday? I tried calling....but no one answers. Left message....but no one returns calls. They need to notify people when mail will not be delivered. Put it on the local News! Something!! This is not good....not professional.

You wonder why the USPS is going broke. I have been calling all the numbers listed for the Sioux City PO for 2 months and NO ANSWER. Also, their mail box is ALWAYS full and cannot take messages. I'm trying to get new mail service for new construction and NOBODY will respond. So, I called the 800 number and sat on hold for 30 minutes. All they could do was to give me the same local number that I have been trying for 2 months. NO Email, NO Online ability, NO Phone, NO response.....and you wonder why they have problems.....
