Ducat Noida — regarding bad behaviour with a student

I have attended an online class in ducat, a - 43 & a - 52 near mcdonalds, sector 16, noida, uttar pradesh. There is one teacher who taught python with machine learning to me and other students of the class also. And there is one whatsapp group of our class is made by him and i just wrote a statement about helping to sir regarding network issues and put a question mark at end of that statement and then he will told students that why you put question mark at the end of statement and he told that do you know the meaning of question mark, it means you are in very angry and it's an abusive word that you have someone. And it's not the first time he insulted me in classroom. I don't know what he is but i actually want to file a complaint against him and ducat noida also without knowing background of a teacher and how his/her behaviour against a student or other person is they include as a teacher in their institute.

That's all from my side
