Swiggy — Not delivering product and product consumed by delivery agent

I orderd a pizza and chocklate Sundae from "SWIGGY ONLINE DELIVERY" The DELIVERY AGENT GANESH with Executive ID "169525"
has not delivered and he has eaten himself and updated in App that its delivered. When i called SWIGGY the executive "SUHAIL" dint give any
resolution except a SORRY. IS this the way online services are working are the CUSTOMERs are fool?

Their mistakes why CUSTOMERs should bear?
Why we should be hungry because of him?
Why these people employee these type of ### delivery guys?
