Yes, it is Vector security. I received this call and found out this morning from my husband that it is Vector. He set the alarm off and they called to verify that it was not a break in.
It is Vector Security. Somehow, my name got on their list and I don't live in the state where their services are offered. I called their number back and informed them of what has been happening to me. They took my name and said they would remove me from the list since the wrong name was written down...still makes me wonder how they got my number. Hopefully this will resolve this issue as I've been getting constant phone calls since 03/21/10.
