I received this call too. It was a automated robot person. I called them back and the person who answered was an Indian man with a heavy accent. He hung up on me. I called back and an Indian woman with a heavy accent answered. I told them I was a 16 year old girl and I didn't understand. She asked me for my information and implanted dumb. She then asked for someone who I didn't even know and I told her wrong number. She said she would take my number off her list.
IRS Scammers, say that you are being sued by the IRS and you or your attorney of record must call them back or you are in deep doo doo. Same old Indian or Pakistani scammers with a new number.
Reporting to the police will do absolutely no good they can do nothing, just ignore the call they are scammers the IRS does not contact you by phone for serious matters.
