Who called from 3132094197

It left a voice mail about a loan offer but nothing identifying the caller/organization - spam.

6pm EDT. Called my cell. Answered (caller ID says Detroit, MI) It was a recording saying a friend had referred me to receive a free wireless home security system. I hung up and added another number to the blocked list.

Called my cell. Caller ID said "No name" so I ignored the call. No message left.

Called my cell.  I didn't answer.  No message left.

They did not leave a message; I thought it was business related, since that is my business phone. When I called back, I received a greeting that I could be removed from the list.
