HappyEasyGo — flight ticket refund pending for more than 100 days

I had booked a flight with happyeasygo from vistara airways delhi to bangalore for 22nd march, but due to coronavirus concerns i cancelled the flight with the airline with full refund promised by them on 18th marc. The trip id for my booking with happyeasygo was trip id :[protected].

It has been more than 100 days since my cancellation and the company had promised refund within 45 days which was extended to 90 days but even after that there has been no refund. Tried contacting them via email, phone and twitter but got the same generic reply that the refund is in process. The company has violated it's own refund policy without any proper reply from them
