Hello KittyKatty, you are asking for 2 different situations:
1) if the package reached you already, and you don't like it, you will need to return it to us & bear the return shipping cost; after we received the returned wig, we will issue you refund.
2) if the package never reach you but just returned to us, we will check what's problem with it, if that is not your responsibility, then we will ask if you'd like us to ship to you again (by free shipping, no extra cost needed) or you'd like to get refund directly.
