Swiggy — Missed item in the order

Address: Aditya international school,Idigarai, Coimbatore

On 12/02/2023, 12.15 pm I ordered Butter naan and other side dishes.
While opening the parcel it is observed that main dish was missing.
I called the man who delivered the parcel he told he was not responsible and asked me to call the customer service, customer care told that I am lucky and I am eligible for 30 rupees coupon since one item was missed. I was really hungry and the people in swiggy were playing like anything.
I did not receive the missed qty or money back.
This is my first and worst experience with swiggy.
