OYO - just like always .. hotel denied checkin and oyo denied refund

I booked four rooms for ** guest in Vishal Guest House at Jatni, Khurda Odisha ******.
i made a payment of rs *** and rest payable at hotel (*** net banking and *** OYO money).
called OYO representative around four hours after booking just to ask the confirmation of rooms and he gave me hotel number to contact.
then, around *:** pm when i went to the respective guest house and they denied the check-in.
The reason they provide for denying check-in was unavailabilty of rooms first and then they said they are not getting their base price is higher than the booking amount. the problem was i also used a flipkart coupon to reduce the amount of booking by **%.
and then the OYO customare care suggest my friend (who was complaining about this incident) for paying more money to guest house representative and then finally the guest house didn't agree for any mutual terms.
The problem was my phone got switched off and all the calls were made from my friends phone. so i was not able to lodge any official complaints against guest house.
i tried to chat with oyo represenatative next day but then OYO polocy denied to send me back my booking amount.
This is completely fraud where OYO takes money and hotels most of the time deny the service. Kindly look into this matter. please find the attachment of the bill.
