Here's what I would do and here's why! I'd call FedEx Customer Service and status the package - you'll find the answer in a couple of minutes. If WooAudio has not specified "Signature Requested," you may do so with the representative over the phone if that's your wish.
Sounds like you just wanted dropped, yes? I requested USPS & "Signature Required" for my Woo and Jack obliged. After it finally shipped week 8, I received email notification for FedEx, "Signature Required," so I rolled with it and tracked it. On delivery day, I kept checking, waiting and listening for the truck to come by... and ring the door bell.
Finally, after hearing the truck make a stop down the street, I got excited. But the delivery truck was out of view some three homes away. So, I waited. And waited. No one came to the door or so I thought. And the driver drove off. Jumped on my computer and nothin'! Like an expected father, I paced. Maybe the driver will come back through.
Once I heard the driver leave the general neighborhood, I called. It was a busy Friday but eventually got hold of a rep some 12 minutes later. The rep confirmed the package was left on the doorstep - the website for tracking was behind and didn't show the update. The driver FAILED to ring or knock for a signature. Further, it appears he passed the house, parked and walked the package over and simply left it on the doorstep. I called back to complain and discovered it was a substitute driver - my guy had the day off!
Had someone left with my Woo without me knowing it was out there, I would have called Jack up with no shame at all... "Wassup, baby?! Your amp is missin'!!!"
