Oyo - Hotel price injustice

We checked in hotel sinon, Delhi on *th June and we fully paid the amount **** until * June. But because of the staff behaviour and the lady manager who was extremely rude and abusive with very dirty language always kept shouting, didn’t help us at all whenever we asked the staff change the bed sheet as they were dirty since we checked in and there was no water for one whole day, the door does not get locked we were told that it’s safe and not to lock our room. I’m a girl and I felt very unsafe and uncomfortable by the behaviour. I decided to check out at * June and I left the room at **am. The lady purposely came late and checked us out late (which is considered as another day) and oyo comfirmed that as late check out and is not refunding us the money for two nights. The amount is **** which I need to get. Oyo disagreed to pay and does not even acknowledge all the bullying I had to go through with this hotel sinon. Please help us as they are not paying us anything at all :(
