I've gotten 7 in the past hour from these numbers. Its annoying when I'm at work trying to do what I need to do and my phone rings every couple of minutes. If its truly the Illinois department fo revenue, they would leave a voice mail and a contact number to call back. Whats really annoying is this number started calling at 6 am on saturday morning as well, now I know its prabably a phishing scam.
Numerous phone calls from this number - no response from the other end except hanging up on me. Try calling back and I get the busy signal. Have no clue who it is but they continue to stalk my private cell number.
