Domino's Pizza — no refund received

I placed order through swiggy. My pizza was not delivered and when i called dominos, they informed that they cannot get in touch with delivery guy and order has been cancelled and amount will be refunded but it is still not reversed.
It has already been more than a week that amount is still not reversed. Now when i call. Dominos they dont answer my query. I would like to know when will i get the refund? Because this is not the first time i have faced issue with dominos. This is the swiggy order id [protected]. Swiggy says they cant help with this and we need to directly contact dominos for this and no help received from dominos end. Please check this asap.
