For the past three days I have been unable to log in because of 3102 errors on all NA/EU servers, although I've been able to log into JP servers just fine. SE support has as of yet not respond to my ticket about the 3102 errors.

When I tried to log in today however I received the following error:
You could not log in because the service account in question is not registered. If you would like to log in to the service, please log into the Square Enix Account Management System and register the service account.
However, when I viewed my account services on Mog Station it said that both of my FFXIV service accounts were suspended, and I was not able to take any action on either account (such as registering a payment option).

My question is: Have I been hacked? Was I receiving the 3102 errors because somebody else was on my account? What course of action should I take now to get my account unsuspended/recovered?
