Zomato — zomato food damaged

Today i ordered my lunch from zomato-
The food order i received was not sealed and as it was chicken gravy momos the gravy spilled outside on the package. When i opened to have my lunch there was no gravy in the box. So i raised i complaint on zomato support. I asked them to take this order back. They said it cannot be done. I was told they can refund 40.5rs coupon codes. Zomato is taking customers for granted. Even after complaining they didn’t took the order back. Didnt refunded my money. The order which was suppose to be a gravy item had no gravy left because zomato had no responsibilities to look after what is delivered to customer. They gravy item was packed in a some sort of paper box or something, without any taping to it. Obviously it this had to happen then. After disagreeing on the refunding me my money or taking back the order. I asked the to put me on conference call with restaurant owner. I then received a call from zomato. I explained him that how i received the order. After the whole conversation, he said a full refund would be given to me. After this call again the zomato support person said we are sorry no refund could be made or the order could be replaced we can only add 40.5rs cupon code. My whole lunch time was wasted. I could have my lunch. Zomato forced me to keep the order. I had paid rs 162 for nothing. Attaching all images of the conversation and the food order photo. The order was from zomato by the restaurant-momo addiction satiyaniketan, delhi.
Zomato has started this carless attitude towards their customers. People please think before ordering and please don’t pay online else you would face this what i have faced. Order on cod, if something like this happen don’t accept the order. I had paid already online that is why i was forced to take the order. Which was waste of money and time. And the funny part is zomato order had separate packaging and dilvery charges. Where as if the packing would have been done properly my food would have not been spoiled.
