Caller Id himseld as FedX, and that they were trying to drop off a package. He wanted to verify my address. Later tried calling number back. Call went through, he didn't talk, but I heard alot of talking in background. He hungup without saying a word. When I called back, it went to voicemail, which he never setup, so it hungup on me.

Called to schedule a delivery ( between 7 and  9 PM) when no other service deliveres.
Call back to this number is negative.
No answer and a Voice Mail that is not setup.
Called as Overnight Express.

ID Theft or Collection/RePo?

Any idea?
