another energy comparison spam

I called back number (03) 8202 5020 reached IVR for Let Us Compare.

Caller: Choice Vista or Unity Choice

They call from several different numbers:
(03) 8518 6406
(03) 8103 7059
Please be careful. Ask them for their ABN. That normally makes them go away then block the number. I have had 3 different numbers from this made up company. It doesn’t exist when you google it. Don’t be fooled!! There must be something Australian residents can do about these Indian call centres set up solely to scam money out of unsuspecting folk. If anyone knows of a legal body trying to shut these companies down, I will volunteer my time to help catch them.

Have had 3 calls from this number today with no voice or message at the other end when answered.

Caller: Choice Vista
