I got a call from this mob today on this number. As they used this number to call me i have been ringing them back all day (150+ times). It's been a lot of fun. They've had great conversations with John Whatshisname, Luke Skywalker and Batman. Oh how the tables have turned. Looks like they may have even changed their numbers now as when I call the number doesn't even ring.

Total scam, ringing elderly people in retirement villages . Posing as ATO
BEWARE

Bullsh*t scam by some nasty sh*t praying on fear
Just a scam

This is a very nasty sounding message threatening that the police will call with a warrant for 'your arrest' due to tax evasion - then says that he is from the Australian Tax Office and finishes with 'thank you and you have a very nice day'

Message from the ATO, sounds suspicious
