We got a call from this number today as well. The message manager got it but they did not leave a message. We have had so many calls and we were on the Do Not Call list for all the good it did. Also in Saskatchewan Canada. It seemed once we went on the list our calls multiplied in triplet!
just got the call today, i was out no msg. but I dont know anyone in illinois. I am in Williams Lake BC. I suspect it was another cc card gimick, fraud or real , both equally annoying.
