Pothys — I am complaining about the chudithar material damaged

I have purchased via WhatsApp online shopping and I paid for my package fee plus customs here. When I received my items I got one chudithar was damaged I have messaged them and they said it’s not damaged and nothing wrong with it even I send so many pictures they saying it’s material is like that I never saw material like that in my life. I am trying upload so many pictures but it’s not allowing me. Back side fully damage in the front some stone is damaged and front also have material issue.
