No voicemail left and the phone listed the number as Potential Fraud. I blocked the number.

Had my SAMSUNG voice assistant answer yhe call for me they hung up and didn't reply.

Caller: Scammer claiming with Telstra

Scammer claiming to offer me 50% off my Telstra plan, but I’m not with Telstra

I missed a call from this number 3 times in 2 days. No messages left.

Caller: She said telstra

It's a scam, they wanted me to say yes I'm with telstra.i tsaid I'm with optus and they hanged up.
Very hard to understand English with a accent and she was getting angry.

My phone identified And blocked it a spam. I was waiting for an urgent call so called the number and had an unusual ring time time tone and no one answered

No message left. If I receive a call from a number I don't recognise, I do not answer and wait to see if a message is sent.
