She (foreign voice) said she was from Amazon and was confirming a $1200 purchase. I hung up.

Called about my Telstra account that has a problem. Strange as I don't have an account with telstra. Sounded like the call was coming from West Asia area.

Caller: They said nothing

Total silence. From me and then.

No response, hung up when I said hello

Caller: 0485 971 315

Woman indicated that she was from the Federal Government and investigating suspicious activity on my card—namely did I authorise a $900 payment for Bitcoin? I asked what card, she said no specific card, I asked what bank, she said no particular bank, I asked who she was trying to contact, she did give my name, but the whole thing stank and I told her the only thing suspicious was her call. Not that it makes a difference, but her accent was South Asian. Be wary!
