Submit your query, Ongame looks at this forum and they just recently created an ombudsmen for issues like this. If your innocent, I wish you luck getting your money back.
I will never deposit on an ongame skin. You're owed an explanation at the least.
"OngameClassic" is the 2+2 poster who i think is the ombudsman. You can try Pm'ing him.
You have no clue why they took your money??
edit:I see bobo already steered you where you need to go.
