Extremely disappointing experience with Zepto

So I placed my first order on Zepto with 21 items(my biggest mistake) today, including atta, spices, dal, veggies, and milk. Since it was my first order, I was also supposed to get a gift box. But when the order arrived, I only got the vegetables and milk – most of the items were missing!( total order : rs748 missing:430 approx) Never had such experience with instamart or blinkit. When I complained, pehle sirf atta ka refund diya. Then customer support argued with me saying the delivery guy forgot the bag and they can’t deliver the items again. Itna frustrating tha! After a lot of back and forth, they finally processed a refund for the remaining items, but it came in Zepto cash. Ab mujhe firse baki samaan order karna padega aur dobara handling charges bhi dene padenge. Such a waste of time! On top of that, no gift box ;-; . Pathetic Service
