same as
diedre....have had some very threatening and abusive calls from this number...said his name was Jason....had two more threatening calls today from (02) 2614 03479 but number has been disconnected

Same as above, my elderly mother received a phone call saying it was the ATO and she would be arrested for tax evasion. She took their number and when it was phoned back, they answered saying they were the ATO.

Person (Jason O'Connor )Said he was from ATO tried to tell me the police were notified and a summons was going to be executed regarding Tax. It really sounds like a scam.
