MakeMyTrip India — Refund not issues from 18 days

It has been more than 3 weeks from my original request and almost a week since I raised my concern here, but Make My Trip hasn't responded by any means so far, no emails or call. This is just terrible service!!!

***********
Original request:

Make My Trip has not refunded my money from 18 days now, no calls or responses to multiple support tickets raised!

Here's the context from my 2nd support ticket on 18th, task id[protected]:
"This request is for a booking that was unsuccessful for the same time period 10-12 August, 2022.
Booking id: NF7Q1G5YZP1ENZGR2898
My booking was unsuccessful due to technical issues at your end on 8th August, however an amount of ₹18, 601 was debited and the app had the confirmation on it. Though the app mentioned the refund would be initiated within 2-3 days, I raised a support ticket as well, but that was closed abruptly on 13th Aug without a resolution - miserable Customer experience.
Previous support ticket number:[protected]
I had to spend again and make another flight booking.
I need the refund of Rs. 18, 601/- processed to my bank account ASAP since it's been 10 days now. You can call me on 97433***** or email. Also, I need to know why the app removed the unsuccessful booking from the My Trips page and the support ticket associated with it as well. Tracking all this is important."

I still haven't heard from them by any means. They don't answer calls nor reply to the emails.
