Swiggy — cheating done by swiggy

Address:

Mumbai City, Maharashtra, 40004

I recently ordered food via swiggy from a restaurant i used to order regularly. I ordered for a chicken biryani which was priced same as i regularly order.
When i recieved the order to my shock it was of half the quantity which i regularly order. When i called the restaurant he said he has received half chicken biryani order from swiggy while the pricing was that of full.
This clearly shows how swiggy is cheating its customers by taking full price and delivering half the quantity
