This is a situation you will want to report to our Game Masters, Vanddori. You'll also want to change your battle.net login and password information as soon as possible.
Never, ever, EVER trust anyone with your account name and password. Game Masters should not even need to ever know your password, and it is information that Blizzard employee will
never request from you.
The trading of in-game gold for out of game goods (or vice versa) is strictly prohibited. Game time is an out of game good, as it has a direct out of game currency value and provides a service outside of the game world (access to the servers). As this sort of agreement is a violation of our policies, it is highly unlikely our Game Masters will be able to provide you your gold back.
If your account has been accessed by someone who is not you, then it would be best to take security precautions against this happening again. If you are unable to access your account, please follow the steps below. I cannot guarantee a full restoration, as the situation described may be considered account sharing, but it's possible that given an education, we may still be able to assist.
Best of luck to you.
