OYO Rooms - Looted in hotel booking

I booked oyo hotel for goa (**th Oct to ** Oct) and i paid all amount at the time of booking.
The last very day when i was in between journey a call came from oyo and i was told that your booked room is not available now. After * days of confirmed booked how rooms in hotel could be available. Secondly without consent oyo has shifted me in such a property whose cost was less. But they increase the hotel price from backround. Also oyo representative was not at all helpful. I suffered a lot mentally and financially.
I am attaching the mails for the proofs.
