Swiggy — Ordered full Qty but received half qty

On 01/04/2023 I ordered 05 items out of which 03 items were as per ordered but two items (Veg Noodles and Veg Tandoori Momos) ordered with full quantity but received only half qty. The Charges for Veg Tandoori Momos is Rs.89 for full and Rs. 55 for half and similarly Price for Veg Noodles is Rs. 130 for full and Rs. 70 for half. I immediately raised the concern on their app and write the emails also. I uploaded the pictures of delivered product which completely shows the half qty delivered. But they denied for refund.
