No message, I did not answer.

Just called me.....I did not answer and did not allow it to go to voicemail.  Caller ID said " ILLINOIS CALL".

In the past day, this number called me using two different numbers: 312-614-1113 and 401-354-7252.  Their called ID both times read L7 SCVC Call (all caps).  They have called in the evening, and also in the morning.  I'm also speculating they also have used 417-800-2893, and that caller ID read Customer Srv (all caps).

don't know but they can stop anytime

They call on a daily basis and I never answer, nor do they leave a message. I call back and press 1 to be placed on the do not call list. It never works.
