Who called from 6103971923

Well you are an idiot, its someone calling about an alarm going off....

Because your cell phone number may have been some one else's at one time that was used as an emergency contact number. Just answer it and have them remove your number

I'd imagine Angela will return to the message after nearly four years. I guess better late than never.

It's Vector Security.  I don't have their service, so how did my name get on their list?  I live over 800 miles from their service area.

They keep calling me at work constantly.
