I have received 3 calls today from this number and 3 calls, two days ago. My caller ID identifies this number as Homeland Security. I looked it up online, and only saw the U.S. government Homeland Security department.
They initially ask questions about smoke detectors. Do you have one? Do they have batteries? Do you feel secure in your home? Then they call back and say that you've won a General Electric security system, and your only cost is $30.00 monthly.
