this number is a fraud. I have been working to have it removed. they probably have your crt. card number and are using it to make fraudulent charges on your acct. CALL YOUR BANK AND CREDIT CARD IMMEDIATELY AND GET IT REMOVED. ALSO CHANGE YOUR CREDIT CARD NOW
Uh, the number is connected with the Illinois Department of Revenue; its a phone number for an office which processes state corporate filings. Not a scam, at least for me, I remember filing my LLC application and charging the fees to my cc.
