Who called from 3126003934

I ignored the call from this number because it was out of area. I get too many pest calls. This one was at 10:16 pm.

Caller ID says "CHICGOZNO1  IL"  Chicago is No 1?  No one left a message.

Caller id "Illinois Call"
Left no message

No one speaks then the call ended

Got a call from this number while I was in class. Comes up as Illinois Call.. I never answer if I don't recognize the number, but incessant calling is annoying and unnecessary. Their number comes up as someone calling from some building off Wacker Ave. in Chicago. Definitely a telemarketing call.
