Haha, this happened to me a while back, I just did a charge back on my card. No need wasting my time filing out forms when the game doesn't work, I always chargeback whenever it doesn't work.
Idk if you're using a credit card to pay but if you are, you might be able to do the same too.
My bank knows I'm not lying since I use my business credit card for mostly everything nowadays, so it always goes through. Then again I don't even buy gralats unless I'm too lazy to hustle for shells.
