I ordered one mango dress in sale on myntra for small size. Now i want to exchange it with m size. Even though that m size is available, but they r not showing it in exchange option stating that can’t delivery to that address.
But if go for fresh order they r ready to deliver m size on same address on undiscounted rate.
Kindly help coz even if i buy that product in sale, i have right to exchange. And if that size is available they should exchange my product with desired size
