Who called from 6616063918

Did not leave a message.  Called back and says number out of service

High school SAT study tools? Called before various times and only heard laughter on their end of the phone. Seemed very sketchy giving information about the SAT's.

Same as the first caller I have recieved several calls from this number always hang ups when called back said number disconnected

Call back gets, "we're sorry, the number you have dialed has been disconnected or is not in service."  That means it's spoofed.  That means it's a SCAM.  Block it.

Been calling for a couple of months now, I never responded. Arvin, CA  is the supposed starting point.
