I also just received the call that the IRS is suing me and to call them back. I received other calls like this from other numbers, I wish they would stop!
Recording of a man with some sort or southern (?) accent claiming to be a police with the IRS with a warrant for my arrest??? Come and get me then or have a human call if that's the case! Abusive scam!! I hate these because its conscientious people who get taken in.
