My dog is dying because of you!!


Commerce city post office Lost 1 full week of mail for my whole trailer park. Then lied and covered up meanwhile the postmaster must be involved because he won't respond. And the evening supervisor named Caleena made an false report to the police to further her cover up of the mail theft.


Due to medical issues, I can't get to the mailbox. The carrier said with permission from the post office, I could get the mailbox moved to the porch. I have a note from my Primary Doctor. Just need your okay. Kathy Brooker 8125 Krameria Street Commerce City, CO 80022 303-960-5514


on 3/21 i had a noticed left in my mail box saying that i have 2 registered letters at the post office, it was marked sorry we missed you. the issue is the mail carrier never even came to my door, i was home all day and i also have a camera and i checked the camera and again the mail carrier never came to my door. all that was done was the for filled out and put in my mail box. i feel they should have to be redelivered.


We have a key for mailbox D for a package that we were waiting for but when we put in the key it jammed and will not open. The key and our package at stuck. Please help! 12/23/19 6pm


We had a key in our mailbox today, inverted it into the package slot. But it froze an will not open. I fear the wrong key is in the wrong lock. Very sorry for inconvenience this may cause our mail carrier. Is it possible for this package could be brought to our pouch? Again I am very sorry, didn’t have my glasses on when I used the key. Mail for the McCorry /Frank resident.


Every time a package of ours hit your department it is delayed by three or five days why. Your the only department not Colo. Springs just you?? Wish you would upgrade your system there it I'd bad I am sorry to say!!!
