how to recover deleted data

I accidentally deleted a collection and the datasets in the collection. When the collection has a notification saying that the dataset has been deleted, I click the undelete button and it says “failed.” Is there any other way to recover the deleted data? I went into deleted or hidden and it wasn’t there either. I don’t recall every selecting permanently delete either.
Thanks!

Hi @biostaring,
could you provide me your user ID, perhaps it would be possible to recover it.
