Flipkart — Unable to log in on Flipkart

I haven’t used Flipkart in a long time. Now I wish to sign in on Flipkart again. When I try to login in with my phone number, it asks for my password which I don’t remember as it has been a while. Ideally, I should be getting an option to reset password or authentication using OTP. The only option that’s there is ‘Contact Customer Care’ which doesn’t really help as they don’t have any means where I can report my problem. I talked to Flipkart Support on Twitter but they were of no help.
