Meh.. you can't do anything since they own the account now. It's probably a sign to move forward in life and do different things on your free time rather than playing Graal Classic, You should try to do more things with the people around you and be close friends to them.

I had moved on from playing Graal, Even though I come to this Forum now and then but mostly I don't know what's happening in the game. Take it as a sign lol.
