I am studying data mining in a college in Nepal. In Nepal, students and teachers communicate using Facebook Messenger. Teachers don't share email, and are instead friends with students on Facebook.
I asked my teacher a question forty days ago. He saw the message but didn't respond. Later, I reminded him a week after that. He said "study yourself, find yourself, read books, youtube, google, learn yourself". I told him that I had googled that question, already read books, asked in Quora, Stack Exchange, Reddit, and found no where. Then he responded "Ok I will send the answer".
Then one month went by and he still hadn't sent the answer. Then today, I again reminded him "if he had forgotten about it" (after one month), he saw the message but didn't respond.
What kind of behaviour is this? What should I do in this case? I am considering asking my parents to talk with this professor. Is that right thing to do? What should I do?
This teacher holds a good chunk of internal marks this semester, almost 125 marks. Should I not tell anything to him due to these internal marks, or should I ask my parents to talk to him? Due to covid, face to face interaction is not possible currently.
Professor not replying to my email
This doesn't answer my question because he recommends to go to teacher physically, it is not possible at the moment due to covid.
