Flipkart — Flipkart travel is not refunding my money for cancelled flight

Hi, I have booked my flight from Flipkart on 04th Feb 2020 from Bengaluru to Kolkata for 16 Apr 2020. Due to pandemic the flight got cancelled. On 20th Jan 2021 Airsia has refunded the money to Flipkart but Flipkart did not refund to me till date. When ever I am calling Flipkart customer care, they are disconnecting the phone after hearing flight refund.
