Swiggy — Delivery not delivered

Ordered sweets and was to be delivered at my father's location. He was not aware of delivery so he returned. The delivery boy set the status as delivered. The item was prepaid. SInce then he is not picking call though he had called twice to understand the address. Swiggy chat is not supporting as it says the order has been delivered. Delivery boy's no is [protected]
