Received call on cell phone, didn't answer. No left message.  Anyone else own businesses and/or registered via websites and haave business licenses? This might be where they got the info.

Received the call on cell phone - was on another call so didn't answer; no message

Identified themselves as ASG Security, and wanted to come to my home, by appointment.  When I returned the call, it was disconnected. When I called the main number listed on their website, the offices were closed.
