fyi - When you call these jerks back, you have just made it okay for them to hound you forever. All they need is that ONE call from you (even if they say it's to get off their call list). Then they can claim you have a previous business relationship, because they now have a record of YOU calling THEM. Duh.
8/5 11:15 I just got a call also. ID says New York. No message left. The way I see these things lately is that if it really means something they would identify themselves and leave a message, therefore, not worth my time or energy, except to tell others.
