Caller: Apparently an energy. Company

Most likely scammers as they hung up once I picked up or they realised I was driving.
Ringing back you get to a recorded message whilst on hold.

As soon as we hear the delay on answering we just hang up & block!

Had a call from this interstate number for me, didn't answer

Claiming they were trying to sell cheap finance - just hung up - suspected scam to get personal details.
