[Resolved]  Oyo Rooms — denies check-in on confirm booking - hotel kalyan palace (oyo 39358), ujjain

I had a confirmed booking from oyo rooms booking ref xsmg4291 for 10 people (4 rooms, 4 days) at hoel kalyan palace (Oyo 39358), ujjain. I had also confirmed the booking over phone with the hotel manager on the booking date, but the hotel denying the check-in and said that they cannot provide any rooms as they were full. I am calling the customer care for more than 2 hours, all the times they told that they are transferring the calls to their senior as they can not do anything but i am surprised that every time after waiting 10 mins the call got disconnected automatically. One time they transferred my calls to one of the customer not to their seniors. Some of the customer care executives are-bhushan, silvia, satish gupta and kiran. All o[censored]s waiting outside the hotel for resolution and getting tired as we are stuck after a long journey (30 hrs).
Please suggest what can we do. Is there any regulatory authority to handle this?
