Who called from 4707750259

Just got a call, and it wasn't even a call that registered on my work phone. There was a voice mail left and all it said was your request to be removed from our call list will be fulfilled immediately.
Very strange as I have no idea what this number is even for. Don't care really, they are "removing me" so, good on that I suppose.

Called me at 2:19am. Recorded message "your request to be removed from our call list will be fulfilled immediately"

Me too called @ 2:25 am pdt dicks

called at 5:20am and 5:21am PDT, no message

"Missed Call" per Google Voice - means they hung up on challenge. Sign of a scammer...
