This person (a woman) called me multiple times, speaking in Chinese. At first I didn't answer. When I did answer, there was a quick beep, and the person started speaking in Chinese. I immediately hung up. The same person called again, and in Chinese, she asked me why I hung up. I spoke in English and asked who she was. She immediately hung up. Another number she used to call was (02) 9067 8411 and (02) 9067 8252.

Same as above. Said calling from some Chinese company or body, and first think he asked, can you speak Chinese, and I said no, and he hung up.
