Myntra.com — instead of catwalk sandals a used golden sandal delivered to me

Address: 123 A triweni colony indore, Indore, Madhya Pradesh, 452001

I had received the parcel yesterday of my ordered catwalk sandal and i opened it in front of the myntra courier agent and he saw that the product i received was a golden sandal that seems to be used already. Then he told me that i should opt for a return under the wrong product delivered category and i did so but now the company says they are not liable for this.. Why don’t they just ask their own employ to tell what he saw when we opened the product.
