Compromised Account Permanently Disabled?

My gf's account was recently compromised, a day or two ago she tried to log into the game and received the message that her account was on a 24 hour suspension. She has since changed her password, scans on her pc come up clean, etc. She emailed wowaccount admin to request character restoration, today she received an email for each character that had been restored, however when logging into the game she still gets a message saying that the account is temporarily disabled. When logging into account management it says the account is permanently disabled.

Why would the account go from 24 hour to permanently banned when there was no activity during that time?
Why would they restore characters to an account that was permanently banned?
What's going on here?

If a blue can help that would be great. The main character on her account is a level 80 gnome mage, Bunky on Vek'nilash. Yes, she has emailed wowaccountadmin about this, but as always, there's no telling how long it could take to get a response from them.

Edit:
She also never received an email stating the reason for the permaban, it simply went from 24 hour suspension to permaban with no warning, I was under the impression that you would always receive an email stating the reason for the ban, for example: exploiting the economy, spamming, etc.
