Had two calls from 312-248-9227 on 10/13/15; one at 5:40 PM, and the other at 6:19 PM.  We NEVER answer calls from names/numbers/companies that we do not recognize, so the calls were picked up by our answering machine, but no messages were left-- caller merely hung up.  Presuming that they are scammers?  These calls are SO annoying!
