Swiggy — Half the quantity received

Address: Andheri West, Mumbai

I ordered a Nutella slice cheese cake from Boston Cafe through Swiggy and paid Rs.292 through Paytm in advance. after I received the order I saw that the cheesecake was only a half slice and not the full slice. it was not only half the quantity of what was promised but also very uneven in the toppings. the issue is still unresolved
