I ordered a package 2 weeks ago that I purchased with 2-3 day shipping and still haven't seen it, and not a single update on my usps website either. I just want my damn package!


I have tried to call the number that is listed on this webpage and it goes to a mobile service and they're not answering the phone. My package has been stuck in Casper and has not moved. The postal service altogether is horrible from the one 800 number to this local office.


Really bad service in Casper. Everything from slow to undelivered to misdelivered mail happens daily. its really sad.


yes this is a very sad postal service here in Casper Wy. I sent my mom a birthday card to Iowa 10 days ago & she has still not received it , it's only a 11 hour drive to moms house from Casper where in the f*** is her birthday card her birthday was over with 4 days ago . I will never mail anything again!!

Very poor service from Casper, Wyoming post offices. They have virtually ruined my metrics as a merchant for undelivered merchandise, not up dating tracking information and snot attitude. No wonder the postal service is going under with grunge like this running post offices!!!
