    Anonymous : Sep 21, 2017 at 04:30 am IRS scam. Caller Message: Of IRS. We have just got a notification regarding your tax filings in the headquarters which will get expired at the next 24 working hours and once it get expired then you will be taken under custody from the local cops since there are four serious allegations pressed on your name in this moment. We'd request you to get us back before taking any action against 24, so that we could discuss. The number to reach us is 331-462-2291. 331-462-2291 is repeated by me. Thank you.
