Idp Ielts — rude behavior speaking interviewers

I am disappointed by my speaking test in inviglator that was held at patiala recently. He was behaving badly and taking my interview very speedily and just in 6-7 minutes he finished it. I'm so obstructed by my result. He's an indian, i'm requesting the authorities to look into the matter and take an immediate action against such type of interviewers.

Thanks
