Caller: Guy called himself Michael

I had this number call me twice, so I called him back he claims to be from a energy company and he knows my phone number and my address to home talking to me about the government rebate on solar panels, he even knows how much solar panels I have at home. Is this guy legit, he sounded like either Sri Lankan or Indian

Asian woman claiming to be from my energy company insisting my rates were going up and trying to switch me onto a better plan (couldnt give me the name of my energy supplier when quizzed)

Caller: Alan

Alan called. Claimed to be able to reduce my electricity bill. I had stupidly called back an unknown mobile phone number. Now had 2 further calls. Told him to 'clear off'.

I called back the number 0414 868 771 and the lady on the other line did not mention the company name

Caller: A person called himself Mark

Knows my name and claim from Energy Australia. I simply hung up.
