Who called from 3126141113

This number has called me over 10 times in 4 days.  I have blocked it and then another number just like it calls me.  It's getting very annoying.

Called said they were National Security Systems want to sell us bogus software asked questions about family, computers, trying to dial into our fonebox scam scam scam phishers looking to make CC profiles to drain your Bank Accounts report to FBI

Had a similar experience to "Bothered" (see message below) where I received a call from this number (312)614-1113 and I said "hello" and the person (computer?) on the other end of the line hung up...and then within 10 minutes I received a phone call from (401)354-7252 and they also hung up as soon as I said "hello".

3 calls today stopped by call blocker

This number calls me all the time. Sometimes more than once a day, then nothing for a week. If I answer no one is there. It has left voicemail with nothing on it several times.
