Jubilant Foodworks Limited — Payment transferred but order not delivered

I had placed an order for Rs 172 on the dominos app on 24th Aug. App not asked the address and linked the wrong address while ordering. Immediately when I call the restaurant on the number mentioned on the App it does not have an incoming call thus I'm not able to contact the restaurant. When the delivery boy calls me, I explain to him the situation then, I have a conversation with one of the people in the restaurant from the delivery boy's phone. He said I have cancelled your order refund will be completed in 2 days but still refund is not completed and on App, it is showing order is delivered.
