To Whom may concern,
This is a nostraliurs palyers, I was just recently (today)banned because I was told that I was AFK at AV when its battling, the truth was I was just left in a while to collect my stuff from express downstairs, my kid (who is just 4 years old) played my character, and just walk around, my kid didn't know how to reply and haven't know idea about english at all, When i came back, i found that I was banned because AFK, therefore, here I am, ask to get my account back. I never did something wrong in the game.
