James Davis

Has anyone been contacted by a James Davis with a call back of 646-783-4922? My husband was called several times a few months ago by a Davis but we cant remember the first name. It was the same as everyone else... gonna get thrown in jail...arrested at wrk..blah blah. Today he was called at work again with the name of James Davis and a call back numb of that 646.... When I try to call it back I either get a busy signal or I get the recording stating that ext such n such is busy. The ext number is like 6 digits. Just trying to see if this is the Insta Cash crap again. We are kinda worried as he works at a state prison and he isn't supposed to recieve calls while at work.
