Caller: A scammer claiming to represent the ATO

The call starts with a robot voice saying that there is a court case against me and to press 1 to discuss further. After pressing 1 I was connected to an agent who asked me for my name. I gave him a false name and he kept insisting that I was not giving him my real name. I asked him whether he was a scammer but he claimed to not know what a scammer is. After about 7 minutes of wasting his time, he insulted me and then hung up .
