Byju's — Not received refund and cancellation

On 28th October i received a call from Byju's DSSL program which occured in our school. They said we got a scholarship, and we set up a meeting the next day.
The next day, we talked to them, and decided to try it as they mention there is a trial period of 14 days, and i can cancel and will get complete refund.
I paid the money of 12000 rupees.

My counsellors (Arun Bikash Chakraborty and Mrityunjoy Chakraborty) told me to use the Think and Learn Pvt. Ltd. App, but there my account was showing to have expired, i couldn't do anything. I have multiple requests for cancellation since then, called the cancellation department several times, even emailed multiple times, but no response.

I have already paid 12000 rupees and now neither am i getting any refund nor my course is been cancelled,
In the helpline they always say that they would set-up a callback, which i was supposed to receive by 24-48 hours, but i never received it.
As per the terms and conditions, i was supposed to have complete refund if i were within trial period, and i would get proper customer care and all, but all was fake.
I am not able to cancel by any means!
The councillors aren't picking up the calls anymore, I have prove of each and every call recording and all procedures, now its getting too much, I want instant refund or i am bound to go to consumer court.

Most important of all I didnt received any items or content at all!
WHY SHOULD I PAY THE EMI???
I have posted in all my social media accounts and now i will expose you all!
