I gave my sister a skin the name is: Herzchen: and she changed her user name and I sent the skin with the old user name, what should I do now because it doesn't arrive and my V bucks are gone
What you can do
Either keep mourning or consider the point that it will still arrive, because the account will still remain if the name was changed.
The problem is with the list where you choose who to send the gift to, the old and the new name are shown to me but I didn't know that she had changed her name
Has it been sent yet?
Yes, unfortunately
And your sister wasn't kidding you?
It can't go to nowhere…
No, I can see on your switch that nothing has arrived and that it has a different name
Can I recall the gift in the settings?
No, unfortunately, gifts can't be returned
