Who called from 2066298639

I receive a call from this number, pick up the phone, and a guy yells " DON'T GET SMART WITH ME!! " and then hangs up the phone.  BIZARRE!!

Calls 2-3 times per day, everyday, even Sunday.  Never leaves a message and will automatically hang up when I answer.  I have never had a real person on the other end.  I tried calling them back and got a message that the voice mail is full.

I think its some kind of system to verify if the number is active or not

calls, asks for me, is told I'm not here, hangs up

Received a call, no one said anything when I answered, could tell someone was still on the line.
