This is BOGUS. I received an automated call telling me to call this number because they were the IRS and were going to file a lawsuit against me. I called the number, and a man with a heavy foreign accent answered, with no official greeting identifying who I was calling. I asked "who am I calling?" and he said "IRS." I said so you work for the federal government? He said, "yes." I said, "you do, do you. May I please have your name?" He hung up. Completely bogus. Don't even bother calling them back. Had I sounded frightened or something they probably would have tried to extort money out of me.
