Oyo Rooms — Refund is not credited in my Bank Account

I have made booking through OYO, Booking ID: BEKL1803.
I have cancelled the booking they told me that i will get refund in 7-14 days.
after mailing them more than 50 times. They made me trapped in their process. And on 18 April approx. 1 month they mailed me and asked my bank account details. I gave them my details.
and they refunded the amount in my oyo wallet instead of my bank account.
felt cheated as my money is still with them only
