Swiggy - regarding swiggy cheating on customers with bad quality food and fake discounts

I ordered an egg biryani from swiggy restaurant named dieto cafe (Dilshad-gardens). They kept the food cost *** and cut it and kept *** Rs on it. So I thought that they are giving the discount and proceeded to order later on as soon as the food came I opened firstly I shocked to that disgusting small quantity they are giving. Next, the main thing is when I kept a single spoon I came to know the smelly kind and food is spoiled. I have suffered a lot my hunger is spoiled and it is pain for me. They keep fake discounts and they are providing cheap food and spoiled food by playing with customers health. They are not sending any of their delivery person to verify nor paying compensation to me. Imagine my pain of hunger and throwing spoiled food. Order number: #***********
