Oyo Rooms — No credit of refund

I have not been refunded amount regarding my booking. I was denied checkin by the hotel staff reason being that they had not received the booking amount from the company side. I had paid at the time of booking but still was denied checkin and was told that I would refunded within 7 to 14 days. Its been about a month and still not received amount in my source account. Customer care did not transfer my call to the concerned department. I am attaching my details:
Name - Rahul Kumar
Booking Id - TT6K3711
Booking Date - 20th May, 2020
