They called and I got an automated message saying that I was being sued by the IRS and to call the number for details. I called and they asked for my name and then for my phone number. I gave them the information and was told I was being put on hold so they could process the information. So I get put on "hold" and the line disconnects. Tried calling them back and it rings once before going to the busy tone. The number was 2062012258. Should I be worried about this? Has anyone noticed like identity theft or anything else because I'm part of a low income family and I seriously can't afford for something like that to happen.

No, please call the 1800 number above. This is a scam. Please, do NOT give them any of your info.

I got the same call a message was left saying for me to call this number as the IRS is filing a law suit on me.   I callled the number and he basically told me if I dont pay or make a promise to pay I would be arrested in the morning by the local sherriff.    He then said he would talk to his officer and call me back in a hour.

Please don't give them any information. If you do talk them again let them know you are contacting the Attorney General. The phone number is 1 800 366 4484.
I got that number from an IRS agent.
