hacks

few minutes ago I was just filling my freshly bought tiamat guard's set with manastones when a AM wrote on me with reason that I'm using some kind of hack program... and I've to follow his instructions if not he will ban my account. If I don't want get ban I've to give my ID, PW that he could check my ?? history.... and he said I've 59second until banning...
I've read many of posts that I shouldn't give to anyone to my id or pw because if I loose my account that will be my responsibility. I didn't know what to do just logged out from the game. But now I'm worried I've this account since 3years and I've spent on it so much time and money (abg set).
I don't think so this men was a real AM .... Please help me! :'(

If he tries contacting you again, take a screenshot and post it under the in-game reports section along with the server in which this happened.
