I'm guessing you play EE? Whichever game it is, the first thing to do if you suspect a hack is to first change your password
if you are able to. Secondly contact a Game Master by sending in a ticket by using the Contact Us
form. You'll need to include in the ticket character names, gears & lvls if you can remember, i.e. any information to prove the hacked/stolen account is yours & they will reply with steps to recover it to your email within probably 42hours. I hope this helps a bit, good luck!
