Indigo Airlines — not approving cancellation

I am trying to cancel my booking with indigo airlines. But the website is not allowing me to cancel the booking. So i tried calling them no answer due to covid-19 situation and suggested to chat with them on the website. I have spent 1hr chatting with them and requested to cancel the booking. Three advisors chat with me and no helped me to cancel the booking finally one guy helped. But in the end i realised he has lied that he has cancelled my booking.
