Australia Reverse Phone Lookup

A female with possibly a Dutch accent rang me twice, simultaneously on my mobile and home number. There was no one on the phone that end on the first call. She claimed to be from the Australian Taxation Office. She advised me in an official like voice that I am being charged with Tax Fraud, there was a warrant out for me and she wanted to know if I was using a criminal lawyer. I answered "no" and asked for papers to me sent to me directly. "No, This is why I am calling you", she said. I then called her a liar and hung up. I am very meticulous with my Tax records. I don't fear the ATO.
