"Account has been closed"

Hi,
My account has been closed with my Warrior 60 "Elleh" on PVP server.
This morning a GM told me to don't afk on alterac cause i was afk few minutes. And he say it was just a warning.
But after I was playing normaly a Alterac and now my account is closed.
I don't uderstand, I was afk only one time and i'm sorry for that.
Can I have more informations. I'm realy sad for this ban...
Best regards and sorry for my english.
