I did book a room from OYO rooms trough Agoda website (third party website). Booking is for 3 nights and the total price I paid while booking itself for 3 nights is 844 INR .
When I reach hotel to checkin they asked me to pay 1600 more as they charge 800 per night but when I showed my confirmed booking they refused to give room.
They won't allow unless I pay the rest of the amount. I was helpless at that time. I tried calling OYO customer care multiple times but no response received.Neither they're refunding the amount nor providing room to stay.
