This number called & didn't leave a message.
Came up as an unknown number.
As per all other comments these scammers seem to have an endless supply of phone numbers. How????
Cannot report these people through Telstra, why not???
Just add these type of calls to my black list

Caller: "commonwealth bank"

yep, a scammer. said they were from the comm bank. I lead them along, they were trying to get out of me what type of phone I had. told them it was a landline and they called me a f*cking idiot and hung up.
