I answered and they hung up?

Just another mob of grubs

Scam - claim they are from Optus

If you call back you can have your number removed from the list by the auto voice, supposedly

They are from Ringwood in VIC

Wanna talk about the electricity, some multi saver thing.

Selling something

Caller: Another Energy Sales Mob

Yet another f*%#ing Indian Call centre ringing and hanging up without leaving a message. They keep calling from a different number so I’ll just keep blocking them. The government really needs to ban this harassment

They called my mobile and when I answered they hung up.
I called back from another phone and it was Ausi Saver (an energy sales business). Pest call!

Electricity sellers
