Second time they've called this month, but they don't try call properly, let it ring not even once before declining, never had a chance to answer nor will they leave voicemails (i wont answer unless i know who they are)

Number has called twice in two days. Missed first call and no voice mail was left. Answered send call, connection was poor and kept dropping out. Caller said they were from Energy Australia, had a Chinese accent, knew my first name and said they need to go through security questions. Hung up and blocked the number.

the above is true for me too, they've called twice recently and have not reached out in any other way. I'm not sure who this is and I no longer answer unknown numbers.

Caller: 0478 997 729

The number 0478 997 729 has been calling me for the past two days. When I answered, no one spoke. I said 'hello' twice during both calls, but there was no response. I have now blocked the number.

0478 997 729 just tried to call me. The phone rang a few times and cut out. No message left by them. I didn't answer and nor will I ring back.

Second time ringing in the past several days. I picked up the second time and they said "Hello this is Energy Australia, is this [?bunnerong?] housing corp limited?"

As I am not connected to Energy Australia for any services and they had the wrong name, I laughed and hung up.

I got a call, I answered it. It was some Asian lady claiming to be essential energy. She knew my first name, asked if that's who I was. They had a bad line, I could barely hear her. The line went dead after she said it was about a overdue bill. Got called twice now, but I blocked them after the second call.

This is exactly true for me also: "the above is true for me too, they've called twice recently and have not reached out in any other way. I'm not sure who this is and I no longer answer unknown numbers."
