I get calls from this number to on my mobile. I simply disconnect call straight away

These guys call my mobile phone every day for weeks. I'm over it. I've answered twice and they hang up without talking - you can hear them breathing. When I call back, like the others above, they say it's Australian Power and Gas on a recorded message. But is it? Who can we complain to?

My husband and I have been receiving calls from this number so many times, but they never leave a voicemail. So annoying!

got a call form this number, I asked is it for a survey? They hung up. Very Rude!
