I also received several calls from them.
But they are constantly changing phone numbers.
An interesting detail:
They persistently ask what time you'll be at home tomorrow...
In other words, they need to know when you are not at home.
If they call you again tell that you have a home security system.
They call; I pick up, and no one is there. Will no longer pick up phone when I don't recognize the number. I'm very disappointed with the "Do Not Call List" as lately we've been increasingly bothered by calls from unknown sources.
They call every day, pause, and then hang up. They either want to know that I am home (i.e. NOT home), or, they are solicitors who have a quota on how many calls they make. So annoying!!!!!
