Hacked

Yup, was hacked. Just opened an email sent at 4am this morning to my email account requesting a password change. At that point, I knew I had been hacked without logging in. I have again reset my password, but the damage has already been done. All gear/items with a gold value are gone. I logged off last night at about 1130 pm. I also received a 3 hour suspension sometime last night for offering in game gold for real money. Im not a gold farmer in any way shape or form, so I hope this disciplinary action can be removed from my account. Just need to know how to get everything back the way it was. Thanks.
