This number has been calling my unlisted direct line at work once a day for the past week, never leaving a message. Today I finally answered, and it was someone wanting to offer a free wireless security system in exchange for my putting their sign in my yard.
Looking for home to test "FREE" whole house security system. Called twice in less than an hour. I told them both times I'm on the DO NOT CALL register and that no home security system is FREE - it's a scam to get you locked into their monthly high priced monitoring. Both times the woman who called hung up on me - I expect them to call again but I think they're spoofing the phone number on the caller ID.
