As soon as I answered the call a computer generated male voice started telling me that there is a ATO lawsuit pending for me and if I do not call the number that was given (which I cannot recall right now) they will issue an arrest.

same. Threatened that i will be arrested.

Same scam as above threatening law suit and action from ATO if I don't call back

I called back the number (03) 9014 9715 spoke with a lady but couldn't hear her when she mentioned the company name
