...they must be punished.
Consider leaving all your electronic devices at home, spend an afternoon Forest Bathing, and move on.
Anyhow, knowing where you're from might impact the answer to your question, so you're really not helping by remaining vague, purposefully or not. Based on the little information you've provided, it looks like you were just hoping to get better value for your money, which isn't likely to get you much more than a $15 refund, if at all. I feel it's a fairly inexpensive life lesson, you should learn from it.
1. Fight through your Credit Card, Paypal, or whatever payment company you've used;
2. Contact the Better Business Bureau (BBB) or equivalent wherever you are. Even though Wargaming USA isn't accredited by the BBB, they may consider resolving the issue through the BBB;
3. You may have a Consumer Protection Act wherever you are. If so, you may have a Consumer Protection Association or similar, which you may want to contact. There may or may not be conflicting laws issues as the EULA used by Wargaming refers to the laws of California.
Whatever you decide to do, Good luck!
