Oyo Rooms — Refund not received for the extra tarrif paid

I made a transaction for booking a hotel via oyo rooms on 11th july 2022 with transaction amount of 3970/- (3703 from UPI of Punjab National Bank plus 267 from gpay).Paid extra tariff of 1300/- at hotel that is included in 3703/- . It has been more than 14 working days since oyo is telling me that they have initiated the refund and that i will receive the amount within 14 working days. I asked oyo again for telling them that there is no issue from the bank side. Kindly initiate the refund but they are not responding well .
