Oyo Rooms — Booking Details (ID: P4KI6230) not received my refund and unable to reach to the oyo

I booked a room in Hyderabad for 1 week with cost 600 per day and in oyo they asked to pay an advance amount of 1300 and pay remaining 2900 at hotel with Booking Details (ID: P4KI6230) . When I reached the hotel the manager told to pay a amount of 8096Rs i was shocked and tried to call to oyo its not connected for 3 to 4 times after trying so many times i am able to reach them and they called my booking and said that advance payment will be in your account in 48 hours but till now no information about this and no one is picking up the call when i try to call them .
This is very bad part of the Oyo showning low price to hotels and getting the amount from people like me.
Please issue my refund
