Byju's — Not refunding course sold based on false promises

I took byju's vision gate 2024 on the promise that it would better my college performance and its doubt clearing session.The agent got my number from a workshop of theirs, and convinced me to take it as me says its the only way to guarantee in a psu, or to get into IIT m.tech programs. The classes were torturingly hard to follow and it messed up my college studies. I couldn't do anything else other than studies. I was lured into the program and when I wanted to cancel it, they are saying that they can't. They are forcing to continue it which is affecting my mental health. The agent were very deceiving in the way they sold the course such that the non-cancellation policy was graze upon.I think its unfair for not providing a 2 year course a refund also adding that the promises were false and it actually completely destroyed my health. I want atleast a part of the money back.
