Hello:
Translated by machine:
fili#11781, this is my old account and it was hacked, I can’t access it right now, they changed my registration email to one that I don’t know at all, what can I do? I refuse to give up my game and the money I paid to get it.
Nothing can be done on the forums; you will need to submit a ticket to Blizzard Customer Support. See this Support article for details:
Good luck !
