Poor quality productsold and return declined

I have made a purchase from Myntra of 6 beautiful kurtas on 27 June 2019.
Recently, I wore one of the kurta from Vishudh in olive green color heavily
printed golden in a function. To my utter dismay, within few hours of
wearing it, it turned red from the places having golden work from body
sweat. I never expected such a bad quality from these guys.
After months, my return request is rejected with no justification given. This is fraud. They cannot sell this crap for such a high price.
