Who called from 8475829746

THEY KEEP CALLING NOT LEAVING A MESSAGE.

A MAN CALLED ME ON SUNDAY AT 7:30 PM A AND LEFT A MESSAGE SAYING THAT THERE WAS A SERIOUS PROBLEM AND TO CALL THEM BACK.
I AM A SUSPICIOUS TYPE OF PERSON, SO I LOOKED "THEM" UP ON THE INTERNET....
THE # CAME BACK AS BELONGING TO:  
AMERITECH ILLINOIS, IN LAKE FOREST, IL. (I THINK IT SAID THAT THEY ARE A PHONE SERVICE!?!?!?!?    THEIR # IS:   1-847-582-9746.
FURTHER INVESTIGATION REVEILED THEY ARE FROM NETCASH AND ARE A RIPOFF CO.
IT SAID TO NOT CALL THEM BACK!  I DON'T PLAN TO!!!
I AM SENDING THEM TO MY ATTORNEY GENERAL TO MAKE A COMPLAINT.
I ALSO DELETED THEM FROM MY PHONE MACHINE!!! (IT ALSO SAID THAT THEY HAVE TRIED TO CALL ME 14 TIMES!  THE NERVE!!!

Ya that call me like 10 times a week, saying the same thing... i never answer it

Received several calls and no message and not answered because of unknown caller and this happened with several calls.

The phone leaves a message that they are calling about an important business matter.  Then say this about collecting a debt.  They call everyday and I called this number and told them to not call anymore.
