Swiggy — Swiggy Order was missing they have send only box

I have ordered 3 items
1) Amu Butter Pav Bhaji
2) Mix veg Fried Momos (Missing item)
3) Strwaberry Milkshake

I asked customer care executive he said he will refund it. i said i don;t want refund i just want to know what happened to it. I am sure that delivery guy had eaten it because in the box chutney was there but momos was not there..if restaurant not forgot to put chutney how they can forgot to put momos.
My main concern is ... We order food from swiggy with assurance that swiggy is not like Zomato. but if same like Zomato is happening with us then what's the use...
