Don't answer.
Collection Agent

Collection agency collecting old Illinois Tollway fines for not paying toll booth fees.

they call at all hours of the day, including early morning. When you answer all it is digital msg to call them back. this amounts to harassment.

If you can tell em why your calling don't call me. If this is a toll company collecting . I pay tolls so get info correct. calls now fall under harrassment as I jhave no idea who they are and they don't tell you.

This is Arnold Scott Harris, P.C., a debt collection agency in Chicago posing as a law firm.  If they call you, there is a good chance the debt is legitimate, but there is also a possibility that they are trying to scam you.  Beware.
