Accidentally returned a donated item to sender

[Lunastra]

Not sure if this is the right place to post...

So I bought something in the website store for coins, and when I opened up the mail containing the item, I accidentally hit the return button at the bottom of the screen and it just disappeared from my inbox.

Any ideas on how to tackle this situation, and if possible, get the item back in the process? Any help is appreciated :)

It should have been resent to you automatically in half an hour or so.
