This is different

This time they fucked up real bad, with obsidian chest bug you could argue that we players exploited a bug, chest was still 300 gems apiece however you wouldnt get charged. In this occasion however we played the game with their rules, if in the shop we have te possibility to purchase something i don’t understand how we will get punished for doing what you permitted. Moreover, making an ingame purchase is a contract between parties, you cant simply say “no, my mistake, everything is voided” you have obligations you will be hold accountable for. In this situation they need to bite the bullet and move on, from a legal point of view they are in the wrong.
