Caller: Sounded like an Indian woman

Allegedly from the NBN Company. Alleged there was a problem with my NBN. Told her I was not aware of said problem and had not reported anything, therefore not expecting a call. She was very pushy. I told her it sounds like a scam. She became angry and asked me if I was making an allegation against her. I cut the call. She called back on (07) 4943 5839 demanding why I had cut the call. I told her she was rude and cut the call again. She called back again on (07) 4943 2790 and was raging. I asked to speak to her supervisor. She continued to rage. I told her I did not want to speak to her and asked again to speak to her supervisor. She was still ranting when I cut the call.
