Igp — poisonous box delivered (rat eaten) chocolates on father's day gift box

I had placed a order with some dry cashew nuts along with chocolates on father's day through igp and blue dart had delivered the courier

First of all there was a wrong commitment and information provided in delivering the parcel stating the consignee didn't pick up the phone and after lot many escalations finally they delivered

But my parents and i were shocked to see in that well packed box, inside a half eaten chocolate (May be by rat) was there and there was a hole in the box which was nicely wrapped by the vendor as if it can't be noticed by anyone

This is not about money but about the kind of product delivered and also kind of playing with the emotions
