OYO - Won t rescheduley booking

I booked a hotel on oyo. On **th June, ****
**:**PM IST.
Booking details:
*Booking Id*: YM******
*Check-in Date & Time*: ** Jun, **:** PM onwards
*Checkout Date & Time*: ** Jun till **:** AM
*No. of Rooms*: * Classic Room
*Number of Guests*: * guests
*Address*: Adam&#x**;s Bridge International Hotel, Near bharat gas Godown, Opp-Dev Darbar Community Hall,Keshri Nagar, Patna.

I wanted to book it for **th June to **th June , but due to a small mistake , i didn't check the dates before booking and it got booked for **-** June.
As it was booked on the eve of **th June , i couldn't cancel the booking as Oyo has a policy of ***% refund only if the booking is cancelled before *:** AM of the same day of the booking. So they won't give me any refund and it's a big scam as they won't let me reschedule the booking. Pls help
