Male with accent addressed me as Miss Jessica and asked if my day was good. I started laughing, said goodbye and hung up. When I first got this number I discovered it had previously belonged to a Jessica, but that was at least twenty years ago, so these scammers are using very outdated number lists!!
And by the way I’m not and never have been with Optus!!

Hard to work through his accent. Identified as Viktor. Said to be survey. Answered a few generic questions with ranges.

I’ve been receiving calls from 0416 140 579 for couple of days too. I called back once but the phone didn’t connect and no messages are left. Clearly a scam caller. Blocked.

called, no message left, I think they have called a few times

Hung up when I answered.
It's not a real number as it doesn't connect when calling back.
