Swiggy — Haven't received my complete order and swiggy is not giving me my money back

Address: Noida

I had ordered 2 chicken burger, fries and cheese coins from swiggy on 1st august. Delivery guy came and only deliver 2 chicken burger. I quickly uploaded photos and inform swiggy customer care. Instead of fixing the issue or providing me the whole items they said it will take 6-8 hours to check this and noone gotten me back. I got them back next day and asked them to refund the amount worth 245+ Taxes only for the missing items not for the whole order. They clearly denied stated they cannot. There is a kinda scam they are running. Looting their customers for nothing.This isn't about money now this is about scam. I had already filed a complaint in consumer helpline Gov. Now I'm going to file a complaint in online legal India and make it public on social media specially Twitter. Give the money back you have looted from me or I will definitely sue you for your scam.
I have posted screenshots below also.
