Swiggy — Item missing in my order

I ordered food through the Swiggy app from KFC, and my order ID is [protected]. The order included the following items:
• Double Down Burger
• Paneer Zinger Burger (missing item)
• Regular Chicken Popcorn
• Classic Zinger Box
• 3 Tandoori Flavor Dips

However, when the order was delivered, the Paneer Zinger Burger was missing. I noticed this issue while eating and immediately raised a complaint through the Swiggy app. Despite the complaint, Swiggy has not processed any refund for the missing item.
I am seeking a refund for the missing Paneer Zinger Burger and expect this issue to be resolved as quickly as possible.
