Caller: They say ATO

This is a scam! They told me a federal warrant was out for my arrest after auditing my info. I’ve been a career for 2 disabled sons since 2005 and as I’m an auditor and tax agent asked where my notification to audit letter was? They told me they would call back. I’ve then called local police station who verified it is a scam and that I didn’t have a warrant out under my name.
