I turned these pests in to the Illinois Atty General back in 2011 & she ordered to leave me alone.  I have kept a record of their calls since then.  They are obnoxious trolls who might as well be listed in phone directory as 5 Star Trolls instead of 5 Star Roofing because they will never do a roof here. Free advertising goes with it 5 Star Trolls.  They changed their Caller ID to Indiana Call now.
