This is an IRS scammer. Caller request that you call back immediately to avoid a lawsuit from the IRS. But if you call the # back it says that this number is NOT a working number so I dont get it. Why do this if you cant call them back to get scammed? Anyway, the # showed up on my caller ID with the name Rosa Olguin. Just beware. Other Calls I have gotten that have the same message just show up as wireless caller but this time it actually had a name.
