This is an absoulute joke. I've tried submitting multiple support tickets and I've tried asking their Twitter account for support, and I've received nothing in return.
NEVER BUY IAP'S FROM THIS CORRUPT COMPANY!!! I know from looking around online that I'm not the only one that has been completely ignored when something went wrong with my game. Their customer service is non existant!!! I spent $5 and got nothing out of it. What am I supposed to do with only 48 gems?? I think Pixel Gun is a really fun game, but the company behind it is really awful. I advise anyone reading this thread to never ever under any circumstances pay any money for in game items in this game, because if anything goes wrong you're completely out of luck.
