St Courier — Damage delivery of my product

Worst service. 
POD No : [protected]
Please be informed that I have received my courier in damage condition which I have packed in very safe condition. I was really unsatisfied with this service. I could see the booking person throwing the product in the delivery bin while booking . And delivery was one day late which had to be delivered yesterday itself . I need a refund of my damaged product worth Rs. 700, and you have to bear this . 
And you haven't mentioned any description of the product like weight, concern booking person sign nothing .
I have attached the POD copy, product image and courier packing image. 
PFA.And revert asap.
