Swiggy — Few items not delivered in the order and swiggy refused to refund for missing items

I ordered food for my family on 13th May, at 9:40 pm. 1 pizza 1 garlic bread and 3 burgers for each member in the house. When i was tracking my order O saw delivery agent took the longer route and was not moving for almost 10 minutes, my house is in outskirts so there is no traffic in the area so I called he didn't pick up initially and later said he is coming but he didn't move for 5 minutes and after 5-10 minutes he moved which made suspicious already so reached oùt to swiggy support but they didn't help as usual later my order was delivered but the 2 items were missing I stopped the delivery agent and asked him if the restaurant gave him the complete order he said yes but I didn't believe him because 2 burgers were missing I clicked pictures of the package and him because I know swiggy support will ask for pictures and even the delivery boy said "madam Order pura nhi dia aapko" when I reached out to support they didn't connect me to support agent on call after multiple attempts I received call from them but they said please email us to [protected]@swiggy.in as we can not provide any solution. I emailed them with all the proves and the delivery agent number but they refused to refund me and I asked refund only for the items not delivered but still they refused. I even asked them many times to share restaurant's contact so that I can ask them but they refused to give that also so I got furious as this was not the solution i was looking for it was a crystal clear case few items were not delivered and atleast they should refund for that. Swiggy is a money eater they keep the money for the services which are not provided to the customer. Very unethical, this is not first time swiggy scammed me so I had to file complain against them.
