Oyo Rooms — Extra money was charged when I reached hotel for checkin saying its low tariff booking

I booked a room in hotel oyo flagship 807771 midnight inn on 30th April through oyo app. My booking ID is O33Z6092. I paid booking amount through app but when I reached hotel, they told me that booking is invalid and if I want to checkin I will have to pay extra tariff charges which is not mentioned anywhere in the oyo. As I had no other option, I had to pay extra charges i.e. 1076₹ apart from 424₹ which I paid while booking, so total bill was summed up to 1500. When I asked for bill, they told me that they will provide at checkout but during checkout manager was not there and also support staff was not ready to give bill. Even though I am sharing screenshot of payment done by me. This is totally not expected from oyo. I just want refund for extra money that I paid which is 1076₹ as soon as possible. Resolve my issue as soon as possible.
