Caller ID says Cherryvale Ks. I always do a quick hangup and notice they usually don't call back, however lately I notice these numbers keep moving around the country with new numbers. It's a vicious cycle and it doesn't help to place them on call block because they just change numbers the next day/week. It's getting frustrating.
I don't think the FCC has any real way of stopping these idiots.

Called at 9:18 this am. I, too, don't answer unknown calls. We are in central NY, was wondering what their calling area is.

I received a call from 620-702-5520 this morning. I answered on the second ring because I want to talk to these people/scammers. The caller ID said unavailable. It was a real person, female voice, American, asking for my husband by name, not Mr. ****. My husband has been deceased for over a year. I made the mistake of saying he was not here and asked if I could take a message. Her answer was, "No. No message." In retrospect, I should have asked who was calling and the nature of their call. I'm seeing the area code is somewhere in Kansas but I know that doesn't mean anything.

Received call at 1204mdt from the number - caller ID had Cherryvale, KS indicated - let it ring - answering machine picked up but as usual these turds don't ever leave a message

left no message
