computer voice ATO scam

Got a call today from this electronic voice and claimed to be from ATO with an "outstanding warrant for arrest" and "petition against our name" for incorrect tax forms and / or invalid tax nonsense call back and give us your details. They announced I was on the Do Not Call Register, which we are. So they shouldn't be calling and since it was a robotic voice, this is a scam. The original number was a private number but they gave me the number I have posted to call them back. Blocked & Deleted.
