How to file a complaint against the visa operator at the Australian Consulate in Shanghai?

Are you sure what you said is true? "I said I was sure, but the operator kept asking. It felt like interrogating a prisoner. I was just applying to travel to Australia. If you are willing to give me a visa, give it to me. If you don't want to give me a visa, forget it. You don't have to keep interrogating like a prisoner. Interrogate me the same way! As a Chinese employee of the consulate, how can his quality be so poor? Moreover, the person's attitude was very arrogant and looked down on others. He thought he was great and was really angry. Please answer her questions well. They kept questioning me with a suspicious tone, and finally refused the visa for no reason. It was a shame for the Chinese people to receive people of this caliber! I wondered how the Australian embassy in Shanghai could treat me so poorly. When hiring qualified people, don’t they care about the character of their recruiters? Complain to the end!
