Xiaomi India — Not getting return of refund

Address:

1, Vijay Nagar Adarsh colony, Lalbagh road

I have ordered redmi note 11t 5g on 17 January but it has been cancelled due to stock unavailability as per told by customer care support so I asked for refund they told me you will get within 24 hours but as today is 21 u didn't get back my refund and now money is stuck . Please give me my return so I can order new phone during the sale which is ongoing . Please today itself as it was sale last day. Please give me back my return .I am requesting you
