Caller: scammer

recorded message and all I heard was, "Message from Kucoin..." then I hung up

Google.blocked the.numbee as potential fraud. Not without reason it appears.

Caller: Scam

A nice robot called Olivia from the Commonwealth Bank called me from some scumbag’s PC sound card. Blocked

Vodafone classified it as 'potential fraud' so did not answer it.

Voicemail left regarding a fraudulent transaction, no name of financial institution, it was a recorded message not a person - obviously a SCAMMER

Caller: Scammer

I answered and they hung up immediately. Blocked after reading the comments here

No message when I didn’t answer.

Missed call from unknown number at 8:30pm.

Caller: Stupid people. Scammers.

The numbers are NOT KNOWN to Google, so why would that number try to ring me? The only confirmation of the number is from websites like this.
Report them to your local authorities, they have reverse contact abilities that confirm the tower used, their origin, whether Telstra Optus Vodaphone or just a computer generated dialer.

Caller: Scummy Scammer

I won a free phone. Just hit the link to claim your prize. SCAM. Dont answer or open the messages sent. Block delete & all contact.
So a definite scammer. How can I win (ANYTHING) if i never entered a competition?

Have no idea. Mystery call
