Zara — Refund related issue

From zara online store i ordered two jeans (order number-[protected]).Both jeans are different from picture.so i visited zara store in my city.but in one jeans inner tag was missing while outer tag was properly fitted (all information was readable in the tag. plus jeans was unused).after that they won't accept my jeans and suggested me to return online.So i make a return request from zara app and jeans was sent to the zara store.yester i got email from zara regarding refund and in the mail they wrote that i cannot get refund because inner tag was missing.but when i received the product that time also the inner tag was missing.product amount(INR 2890)
