Swiggy - Package delivered and took away

I ordered through swiggy for a cake and sandwich which I didn't recieve. In fact they delivered and took it away at the same time saying that the order got cancelled. And there is no refund. I don't understand..Is there no morals?
Moreover the delivery boy shouted at me saying he was waiting and searching somewhere around .and tried to contact me..I didn't recieve a single call. He thought the landmark I provided was my exact location...why should i pay fir the same.?since they themselves day a landmark can be an exact location or a near location. Only after waiting so long I tried to collect his number from the customer service and contacted ..then only he said he had been waiting. I lost my money which they say it's cancellation charge. It's utter injustice. Why should I pay for their fault. And the worst thing is that after much shouting he took off the package within minutes of handing over to me. I definitely need my money back. It was *.**pm when he came here and shouted from the road ..nonsense.
