[Resolved]  Oyo Rooms — Denial of Check in

I booked two hotel rooms at around 21:00 hrs. on 25-Dec-21 through Oyo at Hotel Park (84293), Varanasi as per the following details,
Check-in:[protected], 12:00 PM onwards
Check-out:[protected] till 11:00 AM
Number of rooms: 2 Classic (2X)
Number of guests: 3
Address: C31/31-A, Englishiya line Near Mahrotra Silk Factory, Station road, Varanasi

I paid booking amount of Rs. 955 and to my surprise when I reached hotel at around 22:00 hrs for check in, I was told all rooms are occupied and I need to cancel my booking. I tried to contact Oyo customer service but here was no proper response. Still I am yet to receive refund of my booking amount.
