How to restore a form's responses that I accidentally deleted?

I meant to delete the selected responses, but i ended up deleting ALL of them. is there any way to go back to a back up for my form?

Are you referring to the Review Me Form in your account?

Sorry, but deleted submissions cannot be recovered.

While deleting you will receive a prompt message to enter your password or asking you if the submissions should actually be deleted? If you agree to the same, only then the submissions will be deleted.

However, you can still obtain the submissions from your notification emails.
