Calls and hangs up when answered

Hangs up on answer

Hangs up when answered. When calling number it is a voice mail for Origin Energy? their website does not list this number in any of their contact details for any department.

I called back number (02) 9506 8100 reached IVR for a company called Origin Energy.

Repeat calls every day for last week, never leaves a message and hangs up if I answer
