UPS did that to a package I was expecting monday from Amazon. Then mysteriously I got a email from Amazon saying it was delivered and opened my door and there it sat. UPS tracking said delivered on tuesday.
Then yesterday they delivered a package to my apt complex office after the office told them they dont accept packages for me the driver came back after the office was closed and left it on their doorstep. The apt manager brought it to me that evening and UPS had left a door tag on my door saying it was left at the office.
