How does someone get back a Yahoo email account that has been hacked when all of their personal info is gone?

I have a friend whose Yahoo account was hacked and they changed her password and personal info so that she cannot get back her password. The problem is that she has a credit card linked to that account and forgot which one it is, so she can't cancel it.
