I have a package that was suppose to be here on 07/09/2026 . It's 07/13/2026 , and still haven't received the package. I already did one reschedule for delivery which was for today . Now, due to their incompetence, i have to reschedule again. The package has been at the Clinton iowa post office since Saturday the 11th of July . I'm happy about one thing, i will no longer have my medication sent via incompetence mail....

neighbors dog running loose, it must've barked at the mail person cause my mail had "dog" on them. Left note I don't have a dog, now I'm getting certified letter from CPD. however mailman won't except sign receipt, I now have to make an appointment, the mailman wrote on paper, or it gets returned.
( Rules must have changed). Seems mail person just wants to be a JERK.
Doberman still running loose, have seen it in a 5 block radius, wonder how many other people have been harassed by there mail carriers over this dumb dog? Anyone else getting letters from CPD?

According to Peggy, more than one piece of tape is unnecessary. Based on this photo, I would be to differ. However, that is not the issue. The issue is the rude manner in which she conducts herself with paying customers.
