Great information.
Thanks for such detailed information.

Look it up here while it was raining and saw it was a scam, so I didn't pick up.

I answered and my trusty Telezapper sounded its tones. Dead silence. Seems like it worked as it should, telling their robodialer that my line is disconnected. Get yourself a Telezapper. They are inexpensive and simple to hook up and use. This is not an advertisement. Really, cross my heart and hope to be put on a 419 scammers call list.

Called up and left no message. Caller ID says 'Hackensack NJ'.
