They said call is from Brand Testers Australia. If you call the number back you get a fax machine whistling tone. Will be reported to the "do not call" authority.

Energy Australia calling - when you call back it gives a pre-recorded message saying they are calling about your energy services, but it is not urgent.They'll just keep calling intermittently if there is some issue.
