Oyo Rooms — NO refund after 30 days

I made a transaction for booking a hotel via Oyo rooms in Delhi, Capital O 10824 Hotel Star Suites with BOOKING ID G0NR1313 for last December 9th till 13th 2022 with transaction amount of 12161/- ( from SBI bank debit card ). I cancelled the booking after staying there on second day since there were no rooms for my family to stay. The same date (11th DEC 2022) called their online help support and he told me the refund 5931/-will be initiated 7-14 working days. Since then Oyo is telling me that they have initiated the refund and that i will receive the amount within 14 working days. They also gave me a reference number and i checked with my bank manager. After confirming with the bank mentioning the transaction the bank says we have already updated your transactions but your biller has not initiated the refund. I asked Oyo again mentioning there is some issue from their end and he hanged on me several times. Kindly initiate the refund but the response from Oyo is same that your bank reference number is so and so and to talk with your bank. I am fed of calling Oyo and again without any worthy results.
