These pricks are trying to pass themselves off as ATO officers and threaten you with arrest if you don't call some number, the call is pre-recorded.
They are not smart enough to hide the number that they use to call you.
I called back about 20 times and on one occasion I asked who I was speaking to and the idiot on the other end said he was my father then hung up.
If these tools call just hang up, they are complete amateurs.
