What happened to Nexon?

I was hacked as well in November, but only lost a level 17 Evolving Ring. I don't/didn't have any "good" items, so I didn't care. But a couple days later, Nexon deactivated my account for "suspicious activity". I would have reactivated the account, but the email provider didn't exist anymore. If only I knew that before (it was my dad's email because I wasn't "old enough" to sign-up way back when).

So I sent a ticket on the 7th of June and all it told me -three days later- Need more info. Sent back my ID and new email, but no actual response. I think the system's been sending emails, but with the dead email provider... I don't even want anything except an email change from them. Is it really that hard to just to change emails?
