Swiggy — Complaint Regarding Missing Item in Order - Request for Refund or Redelivery

Hello team
I had ordered food on Friday i.e. dated as 14th march, 2025 in the Swiggy. But one of the item - Chicken Kebab (5pcs) was missing in the delivery, when I had mailed to Swiggy, they responded back with the below information & they had closed my case:
"Thank you for writing to us, we'll share the feedback with the restaurant considering the responsibility of packing the items lies with them.

Unfortunately, we are unable to process any refund for this order; however, we suggest that you rate the restaurant on the app based on your experience to help them do better. "

Post this I couldn't either write a mail or connect through a phone call.

We request to give back the refund or redeliver our product back to us.
