Myntra.com — Vero moda jeans return rejected

I had initiated return of jeans after trying on due to fit issues. The tags were intact and it was placed in the same plastic packaging it was delivered in. The collection person even checked the tags and took it with them. They returned the product again saying there was a stain whereas the product was unused and wrapped immediately after packing. The stain was present even before the jeans was delivered. I need my refund.
