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!!!
