I called back the number (03) 8372 2157 and reached vm that said I reached Your Home Energy

This number really needs to go on a blocked caller list , average of 7 calls a days , no message and when call back goes to automated answering service that has changed its message to several different company names over the last few weeks - looks to be another local number that dodgy scammers are using

Caller: AGL

I answered this number (03) 8372 2157 and they said they were from AGL offering existing customers new plans.

Caller: Home energy

It goes on an automatic voice message that says welcome yo Choice vista or something similar and it says their energy experts can help us, etc.
