I'm very unhappy right now. I made a purchase in another app because I was promised coins for it, and it never awarded me my coins. When I check the free coin menu, it still says "make any purchase in this app" and clicking it brings me back to the app's page in the app store. Glad it was an app I already use so at least my money went to an app that actually cares about its users. Make this right and I'll change my review.
