No message left so assume scam.

they didn't leave a message so I also assume it's a scam

I returned a call from (02) 9136 2401 but reached vm for Oz Green Homes

No message left

After several calls from them, I answered one. they are an energy comparison company who want to "help" you save money on your power bills.
Not a scam, but extremely annoying.
