Yatra Online / Yatratrip.in — Refund not received for over a year. No response on email / complaint

I have booked a ticket for my aunty to travel from Visakhapatnam to Hyderabad on 20 April, 2021 for Air India(AI - 9537). But it got cancelled by Air India later before two to three days of Travel. I have been following up for refund till then but amount did not refunded till now.

Initially Yatra refund status reads as refund in progress it will take some time to reflect, please come back and check in next 24 hours like that. But now it reads (We cannot find any refund initiation request for the reference number[protected]. If you have cancelled the ticket directly via the airline or the airline has cancelled the flight, please go to 'My bookings', select your booking, and click on 'Claim Refund' to initiate a refund request.
Once the refund is initiated, you will get an SMS and email about the refund details.) as if I did not file any refund. I have got an email as well on 07 August, 2020 with refund number as well. But yet they say now that they are no refunds filed for this booking.

At the same time now I can't see my booking in claim refund as well. Not sure why it did not show my booking if I did not file refund yet. Strangely my earlier communications with Yatra also not listed anymore on Yatra site, they are wiped off.

Couple of weeks back I again tried reaching Yatra and they asked me to share either Passenger Bank Details or Yatra Acct Holder Bank Details to process refund. I replied with my Yatra Acct Holder Bank Details but the response I got is Yatra Acct Holder is not you (the details I shared) but the Passenger. I replied with details of Yatra Acct with screenshot and there after no response at all even after multiple followups almost every day.

Below are my booking details,
