OYO Rooms - Sharing the worst experience we had with Oyo

We are completely upset with the poorest to poorest service provided to us by OYO. I want to gist the events happened in order to understand the agony we had undergone yesterday.
We are ** members adult with * kids less than * years of age. Out of the ** adults, * are above ** years of age out of which * persons are physically handicapped. Since OYO is an esteemed organisation we want to book rooms through OYO and contacted the customer care and they provide us with a number of the person on May first week.

He blocked the rooms and requested us to pay an amount of Rs. ***** and we have paid it through online transfer (Details attached). We dropped down in Calcutta and the rooms we occupied had no issues. From Calcutta to Siliguri, we travelled by train and we reached Siliguri at **.** in the morning. We booked a local cab and we rushed to Gangtok to have sightseeing at the earliest so that our days won't be wasted. In Gangtok, there is a local rule that outside cabs cannot go so our cab driver dropped us at a place called Devolire car Stand and we booked another cab to reach the destination. We called the room person where he shocked us by saying that the property is no longer tied up with OYO, the rooms are filled you don't come. We tried calling Mr Ganesh and he assured there are no such issues and we will confirm the occupancy shortly. The cab driver left us and we were on roads with the luggage from *.**. We kept on calling them and they confirmed that there are some issues with OYO so we cannot get you that room, so we will shortly find some other room. We agreed to what your team advised us. Till * in the extreme cold with kids and adults, we were standing on the road and OYO person confirmed us * rooms at Hotel Chitrakoot. Local taxi person closed the shed and went. We tried to get the local people to help and with their extreme support with luggage and kids, we moved to Hotel Chitrakoot. We got down and we took all the luggage and sent the taxi drivers who came for help. We reached Hotel Chitrakoot around *.** p.m.
When we entered Hotel Chitrakoot again we were denied rooms. We really don't know what to do. All the rooms were closed. Our kids were crying for food and again team members were saying wait for ** minutes your rooms are confirmed. But the receptionist denied saying we have ** rooms and all are booked. Even we said kindly provide us with any room they again made us wait for * hour. We got the room only at **.**. by the time we got our room, all the hotels were closed. OYO people have literally made us beg for food. We requested a hotel where they provided us with the foods that were not used by their customers. Again from Hotel Chitrakoot to Tulip Residency with one cab which we got. We made * rounds for the travel. OYO people have spoiled our entire mood of enjoying the trip. The rooms OYO have to provide in Tulip Residency was really worst, Only * heaters were working out of * and the rooms were very small where only a single person can accommodate.
All of the above your people asking us to pay for the rooms, in which my payment if ***** will be refunded in a week time. What OYO so-called esteemed organised going to do for the agony we all had undergone.

My questions to you

*. I paid ***** a week before my travel. It is OYO responsibility to confirm with the rooms and provided me the confirm booking ID. Under what basis without getting the confirmation from the hotel OYO provided us with the confirm booking id?

*. On what basis OYO booked the second room and why OYO people made us suffer in Hotel Chitrakoot.
