Anyone know anything about Harris & Harris debt collection agency?

They are based in Chicago. I received a voicemail recently about an unpaid speeding ticket for $209 that went to collections. The person on the phone couldn’t tell me any information about this speeding ticket other than it was issued in Shelby County. So unable to tell me the date, car, city or anything. When I called the county I was told there’s no traffic ticket of any kind that was issued to me in 2016. Anyone else experience this? When I google the collection agency it comes up and it seems like I’m speaking with actual employees and their supervisors on the phone. Why would Shelby County use a debt collection agency in Chicago? Do tickets even go to a debt collector? I thought you’d just have a warrant out.
