OYO — Oyo is not refunding the extra paid money at hotel

Booking id -JM117864, I booked hotel of ₹549 on 31 Sep 22 through Oyo application. But I was asked by hotel owner to pay ₹1000 extra to get room at hotel . I paid ₹1000 cash to hotel as talked by Oyo service manager that the extra cash paid money will be refunded within 14 days. It's 16days today but Oyo is not refunding the money nor giving the reason for delay. I called numbers of time to Oyo.
