All's well that ends well.
So in seeing what had actually happened, I decided to take a trip down to the post office that served the area in which I *used* to live (and the address that the shipper had sent to)
Fortunately for me, I remembered the address and had the tracking # and everything else in order.
What had happened was the unit was set to be delivered to 3506 MyOldStreet Way, Mytown ST but the shipping label was kinda trash and it looked like it was going to 3606 - which was a business. A kinda iffy one if I recall correctly...
The package had the "Carrier Leave If No Response" tag on it, but I think the fact that it mistakenly went to a business (who was closed) is what prompted them to take it back to the post office.
So after a long drive, and some patience while the awesome postal worker finally located my package - its back on my bench and in fully functional order again.
Just had a delicious sesh to get reacquainted. Glad to have her back home!
