Question about return

Hi!

I lost a case of iPad and an apple pencil by my mistake. So I ordered them from the official apple site.

However, I found them in my home before the ordered items arrived.

Before the ordered items arrived, I requested return on the order page of apple site.

When I met delivery service person, I asked him to return it to apple, and then he brought the ordered items without return code from apple. I received the return code email from the apple after I already returned the ordered items.

I wonder whether I can complete the return process successfully.
