Damaged Stanley Cup

I bought a Stanley cup online and upon unpacking it had scratches and peeled off colour.I sent them an email asking for an exchange or refund as they sold me damaged goods.They told me they did investigation and their footage shows the cup was not damaged from their side, I damaged it when I unpack with sharp object, so they won'texchange it or refund.I sent them a video that I did when Unpacking as the cup was inside a box, wrapped with a plastic bubble wrap that was not sealed, so I just rolled it off on my bed without using any sharp object.I sent them photos of the scratches and the video.Im soo disappointed and hurt, I feel ****med, that I was sold second hand damaged goods for such a lot of money R1039.
