Myntra.com — crocs exchange issue

Address: Myntra, Ernakulam, Kerala, 686662

Hi sir/madam,

I have ordered a crocs of size 10 by mistake. When the package reached home, my parents received it since i was not at home. By the time i reached home they have removed the tag and the outer package.
Since it was one size larger i have requested for an exchange. Yesterday the delivery guy came with the new package. But while the time of verification they demanded for the outer package cover (Myntra cover). My parents was unaware about the neccessity of it. Am currently in a stage where i cant use the crocs and i lost 2400 rs. The thing i have currently is the unused corcs, the box and the bill.
So kindly do something for the return or exchange for my product. Its a request and am from a middle class family. So this 2500 means a lot for me and i cant let it go. Please i will be waiting for a reply as soon as possible.
