Who called from 3864784568

Yet another call, no msg, blocking this # too

DID NOT PICK UP CALL   GOES TO VOICE MAIL AND THEY WAIT AND HANG UP NO MESSAGE

Same as above.  Caller ID has only New Smyrna Beach, Fl.  I didn't answer and they left no message.

Caller ID says "Out of Area", but this area code+exchange IS in my area. I did not answer, they left no message. Scammers!

They left no message, but I called back (from another line) and auto-greeting says "Thank you for calling Sirius XM. We recently called you about your free trial."
