Byju's — Cancellation and refund

Hi
I am complaining in regards to the cancellation of my course which I opted for. I registered for UPSc, and would not be able to continue. I have been trying to reach my counselors through calls and messages but they aren’t even responding back. This is a very unacceptable behaviour. I have done an initial payment of 15000rs through upi on 4 March. Also there is a loan sanctioned for over 1lac rupees through my mother’s account whose first instalment is due on 7 April 2023. Moreover, I have not received any material and neither want it to to be delivered. These counselors were so so eager to get me registered and not even answering a single call right now. I requested them to proceed with the process of cancellation of the course and process the refund of 15000 rs but no one is reverting back. i called them and emailed them multiple times, but the only response i get is we will call you back in 24 hours- but no response.
Below are the emails of the employees who got me registered:
prachi.[protected]@byjus.com
deepak.[protected]@byjus.com

All i need is my refund of 15000rs and cancellation of the course so that no payments are disbursed from loan account as it is due on 7 april
