We called the main lost and found # last year when I left my pillow @ POR. It of course was closed by the time we realized it was missing, but we left a message describing the item and our return phone #. Before lunch the next day, a Sunday at that, we had a phone call saying the item was found and they would be shipping it out next day mail. Verified the address on file and I was sleeping peacefully again by Tuesday night.
I'm sure someone will be able to along with the main # if you can't find it. Most places transfer everything to the main lost and found at the end of the day. Hope it turns up soon.
