Oyo Rooms — Refund not received and customer service is not responding

I made a booking on oyo app with booking ID UDPY2639, booking was prepaid of ₹1637. Hotel called and asked to cancel as they have stopped receiving booking from Oyo. Oyo states that 100% refund amount will be transferred. Refund status shows successful. Refund should reflect in my bank account within 7-14 working days it states on the app. Now after 25 days of cancellation, the amount has still not reflected in my bank account.
And after more than 20 attempts of trying to reach customer support on +91 [protected] which is provided in the support chat on oyo, which is also the reservation desk they say and everytime they keep the call on hold, saying that they're transferring it to customer support and then disconnect the call.
Now is this customer support? Is this customer care?
Seems like customer harrasment to me honestly.
I want my refund as soon as possible
Contact me on [protected] just in case
