Account Banned

Dear GM
I am speaking on behalf of my friend, character name: Langge, because he doesn't know English very well.
His account was banned on 21 of August, around 9 pm server time, due to forbidden golds transaction. However, he has not been buying gold at all. The trueth was that he borrowed 500g from someone about 2 months ago to buy [Foror's Compendium of Dragon Slaying], as he is the MT for our raid. When he finally earned 500g about 2 weeks ago, he gave 500g back to that person. So the big transaction that you guys detected wasn't forbidden golds transaction at all. Please look into this matter for more details, and hope you can unban him.
Looking forward to your reply,
Kind regards.
