I got a red-light ticket in Chicago over a year ago and ATS sent me a bill for $30, I went ahead and paid it, not realizing at the time as a President's Club member I did not have to. I never bothered pursuing the matter even once I learned I shouldn't have had the fee as a President's Club member.

Yesterday I received a refund check for $30 from them, so apparently Hertz must have gotten on them about charging people who should have never been charged. I had no idea what the check was for until I Googled their name.
