Hello, if you make a mistake in online shopping, you can directly return the wrong product to your seller, and then ask the seller to ship it to you again. And the freight is borne by your seller, because this is caused by their mistakes, and you don't need to bear any expenses. If the seller is willing to exchange the goods for you, if not, you can complain directly to the seller. But it's better to settle it through consultation.

Hope to adopt. Thank you.
