As per my previous to a related phone #:
"Usual Pakistani/Indian 'script-reader' promoting some astonishing & mythical deal - based around massive $$ discounts for changing to their non-existent Electricity provision service"

Caller: Some Australian Energy thing.

I could not understand her. She couldn’t even pronounce my surname correctly. Definitely an unwanted telemarketing call.

Electricity bill spam.

Another annoying energy caller - knows my name.

Electrical

I called back the number (02) 8104 1415 and the guy on the other line did not mention the company name
