I called back, it rang a few times then I got a recorded voice saying “Goodbye” before it disconnected.

Caller: Scammer

Scammer posing as a consultant who could reduce my energy bills
Asked for address and personal details. Gave fake name and local police address, they confirmed they found my 'gas' account and said they could get me onto a cheaper plan, pressing for credit card details.
Be careful

Caller: Call identified being from Ballarat

They have called me twice today and I have ignored it because I screen calls and my phone said "potential fraud." They didn't leave a message so it mustn't be important.
