OYO — Refund initiated but not received

I have booked a room in hyderabad OYO FLAGSHIP 75583 Thatipally mansion on June 30 and July 1 2022. The actual amount on OYO is 1297 byt they charged me 3297 by saying standard charges. So i spoke to OYO manager and they said i will get my refund if i a file a complaint with 48 hours of checkout. So i did. And they initiated my refund of rupees 2000 and said i will get my money back in 7-14 working days and its been 20 days. I haven't received any refund from them and everytime i call them there's no proper response and they put me on hold for 20 minutes and more and dis nothing. I need my money back.
