Caller: Claim they from ATO or your Bank

Scam call saying illegal activity on your bank account & tax file number and something about a "warrant" for arrest. Knew it was a scam call though did press "1" just to see where the call will go. Answered by call centre, a person speaking a foreign language was talking to colleague obviously hadn't realised the call had dropped in, then switched to English. When I finally spoke and asked where they were calling from they ended the call.
