I lost 2 skins

I paid for the voidwalker bundle and the young blood bundle in 2021 summer splash sale and lost the 2 skins from my account. It's just them missing everything else from the bundle is still in my account. I need help getting them back. There are no charms for youngblood blood hound and idk how to prove that I got the bundle but still, at least I want my voidwalker skin back I really loved it and pait a lot of money for that stuff.
