Swiggy - Prepaid Food not delivered

I ordered paneer chilli gravy ,paneer tikka pizza and kadhai paneer from Swiggy for ₹***, which I paid upfront via UPI. A delivery person named Pushpendra Kumar was assigned to deliver my order. He called me once on my registered number for directions, but he seemed intoxicated. He arrived near the mapped location but left without delivering the food. Despite this, Swiggy marked the order as delivered. When I tried calling him again, he did not answer. I then contacted Swiggy’s customer support, who also failed to reach him. However, when I requested a refund via email, Swiggy’s support team denied my claim without any explanation."
