The scenario:

You download a free game app which offers premium "in app purchases" for real money.

You purchase 5000 "gold" for real money to be used in the game.

The game is designed very poorly, and causes accidental and spontaneous "purchases" with your gold to be made, thus wasting it.

You ask support for the gold back. They refuse, claiming "all purchases with gold are final". When you show the details which would make it obvious the purchase with gold was accidental (i.e. it would have no benefit to you in the game), they still refuse.

Upon going on a Facebook group for players of this popular game, you uncover that likely thousands of people have been victimized in this exact same way, due to both the poor app design and the no-refund-of-gold policy. Furthermore, you begin to suspect that this is intentional.

I am of the belief that the company acted illegally for refusing to refund the obvious accidental/unintended purchases with the gold, as the gold cost real money to get, and the app did not provide reasonable protections against accidental purchases (nor is a reasonable refund policy in place for when this occurs).

Is this class action material?
