UPS is making me crazy

Has anyone attempted to send something to my post office via UPS in the last couple of months? I got a notification in the mail today saying they couldn’t deliver, and after phone calls we establish that  they now wouldn’t deliver the package because it’d been over a week since they dropped off the notification and it’s gone into some kind of lost property dead zone. “Please get the original sender to contact us with your correct address,” they said.

Right. I have no fucking idea who the original sender is, or what they’re trying to send me. The only clue they can give me is the initials MPS. This doesn’t clear things up any.

Putting this on the blog because, quite honestly, the mystery is driving me crazy and the alternative is finding my local UPS office and punching someone in the nose.
