[Resolved]  Oyo Rooms — Oyo rooms is charging extra money

I booked a room in oyo hotel london street on 2nd march through oyo app. 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. 700₹ apart from 500₹ which I paid while booking, so total bill was summed up to 1200. They also refused to give me 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 700₹ as soon as possible. I have tried contacted oyo service but it is not worth contacting. Resolve my issue as soon as possible.
