I called back number (03) 8518 6100 reached IVR for Let Us Compare.

Caller: Let Us Compare

Electricity deals, they've been told to stop calling, but keep doing it. A nuisance.
There is a Let Us Compare in the US, not sure if this is a real company Australia or just using the name for scam purposes.

Caller: An Indian Sounding Gentleman

I was eating my breakfast when I got my second call from this number.
First one was 30 minutes earlier and from a different Indian sounding gentleman.
I’m retired and have time to enjoy these calls, when I’m not busy, because I have no intention of giving out my details but like to ‘wind them up’ pretending interest. I concluded the conversation by stating that the time they have spent talking to me means less time they have talking to someone else.
Anyhow, this gentleman was going on about all the money I could be saving on my energy bill but I pointed out that I’m totally all solar (I’m not).
It was fun because he kept calling me by someone else’s name and thought I was in a different state.
When the individuals do call you , have fun with it.
Tell them how much interest you will get on your YouTube channel when you upload the recording.
How much money you hope to make from it.
When you get board, just indicate that your going to press the Red button on your phone.
Hope this helps
