left a message and did not say what it was in reference to.  but you can tell it's a call center as there is a great deal of background noise.

A man who called himself Adrian Young left a message on my answering machine asking me to call him back at 1-877-850-1412 "reference" an 8 digit "ID number".  He did not give any other information, but he sounded very busy and serious.  I concluded he was a scumbag salesman or con man.

The record on my caller ID log was: Toll Free 877-898-5004.

Got call from this number asking for return call --
Of course the call will not be returned, as I do not know the source.

To me, it appears just another nuisance ---  reporting a nuisance number on this database. Hopefully, this helps someone.
