Have had several pre-recorded voice messages. "To notify you The IRS is suing you. Please call back right away for details at 213-453-6708, I repeat...." I figured it was a scam. Thanks to everyone who posted.
Received call "from IRS" that I was going to be arrested and should call this number immediately: 213-453-6708. I'm sure it was a scam! A CPA does my taxes. Stupid people--what a shame that they don't know the Bible says scammers will go to Hell!
