Who called from 7868021795

Called my cell phone - a number I never give out. Didn't answer. They hung up. How did they get a number I never use?

called no message left

In Michigan, just called. No message.

Same here. A call with no message. In AL.

Received call from 786-802-1795 and let it roll to the answering machine.  It did leave a message.  It was for a home security system - press 1 for more information - press 2 to be removed from the call list.  (Like that's gonna happen.  They will remove you from one list and add you to 10 more!)  Call came into work phone, so, no way to block the calls.
