Caller: Claimed as ATO

Presents themselves as calling from ATO and talk for some 3000 AUD debt on my tax affairs from last year. Demand immediate payment and threaten with starting a process the following day with 5 years jail plus 97 000 AUD fine if I don't make a payment immediately. They provided an "alternative option" to bring the money in person in Canberra office within 3 hours (I am in Perth WA). Connected me with a "police officer" from the financial crimes who presented himself as Sergeant Ben Morgan and was quite rude on the phone every time when disagreed with him. They made multiple calls within an hour time at 7am to 8 am, basically constantly calling from 3 different numbers - (02) 6461 2744 (6 calls from this one), (02) 6546 3223 (2 times from this one) and (02) 6626 3823 (once from this one). They had voice-over machine and the on-hold music on the phone (copying the actual melodies from the ATO phone centrals, obviously trying to look realistic.
