Who called from 3129406304

Unwelcome call on my unlisted land line @ 7:25 p.m. on 12/26/2016.  I hate running to see who is calling. This is very annoying. I will block it, but really I can only block 250 calls and I keep getting 5-10 calls a day.This is crazy. Sometimes I delete a number from months ago only to have to re-block it. Some of them are the similar exchanges. Thank you for this site that helps us identify these spam callers.

Claims was the police collecting money for their benefit

This number calls me 5 times a day.  Can you please advise me how to make them stop?  I have registered with the 'Do not call registry'

Chicago news reported a few days ago that this is a scam.  Do not give them any money or personal information.

Got a call from this # at 6:29 p.m. yesterday.  Thought I had blocked it, but I did today.
