anyone know who this is?

Harris & Harris...maybe collection or attorney office.  They just called here for someone in my office

Got a recorded message saying it was a collection service.

Harris and Harris, attorneys for collections. Mine was for a hospital bill.

this number called my cell phone and refused to identify reason for the call. I RAN THE NUMBER ON REVERSE LOOK UP - its listed in a residential neighborhood in Chicago to a person I do not know - but she had my name so this is a very scary and harrassing call. The number on the caller ID was different from the number she gave: 312-348-1536
