I cancelled the booking on the same date due to booked hotel was not exists on provided address and it has been more than working days since oyo is telling me that they have initiated the refund and that i will receive the amount within 7 working days. I asked oyo multiple times that there is no refund received, kindly initiate the refund but the response from oyo is same. I am fed of calling oyo again and again without any worthy results.
