Contaminated food and refund less than paid amount

I ordered a paneer rumali roll...I got my order I started eating it wa stinky first ...I opened the wrap and I saw a hair in my roll...I reached out to Swiggy about the issue ...I paid 178 but they did refund me 177..no compensation ..I was disgusted with the food ...It was sickening ...It was frustrating...I can't talk about the food just thinking about roll makes me nauseous ...I got a very bad experience about the only thing I love most is eating ..and now I got such a bad roll with hair and less refund no compensation for my mental stress and sickness ...it is just out of control ..how can they treat a customer like this ...giving contaminated food and than less refund...
