Robo call saying my I have debt and my TFN has been banned and to prevent things going to caught, to press 1. I was bored so pressed 1 and was transferred to an overseas person who claimed to be from "National Crime Service of Australia". I had muted myself at this point but sounded like he was in a call centre. Eventually, he hung up on me. So I blocked my caller ID and called him back and he answered, didn't say anything, and then hung up on me. So it's not worth your time on this number
