Yatra Online / Yatratrip.in — Tickets not confirmed but amount deducted and still not refunded

I try to book flight ticket on 11 Nov 2022 but payment successful and debited from my account and tickets were not confirmed. I got a mail from them that they will contact the airline to reattempt booking. It’s been more than 48 hours now and still the booking is not confirmed. My travel date is in next 4 days so I can’t wait any longer for them to confirm the booking at the last moment. I am in Europe and can’t take a chance by waiting for last minute tickets comfirmation as I have limited visa. I wrote a mail today asking them not to confirm my booking now and process my refund but I did not receive any reply, so I want yatra to process my full refund on urgent basis as they were not able to confirm my booking and it’s been more than 48 hours.
