Illinois, any one of a number of locations. This one came in 11/26/14, 11:06 AM. No message. Refuse to pick up unsolicited or unauthorized calls. Area codes change almost each time they call. Amazing!! Do they really believe they will have a chat! Real callers will leave message and contact information. Do not encourage these people; do not return calls as you don't want to provide any more information for their arsenal.
They call every day and sometimes 2-3 times a day. I have caller I.D. and they read as anonymous. Apparently they think it's none of my business who's calling me, and trying to enter my home uninvited via the phone line. I never answer to anyone I don't know. They never leave a message. I'm on the do not call list, but that's apparently meaningless. I'm going to have to buy me a very loud whistle or a bullhorn so I can greet these harassing scammers/spammers with a proper and well deserved greeting.
