I never did this before but yesterday I was looking for a new wallpaper app. I downloaded "Top Chart of Wallpapers & Themes," by Victor Ershov. The app immediately asked me for a bunch of permissions which I of course denied and it's not a problem, a lot of apps do that. But what bothers me is that soon after I had a bunch of ads covering the entire screen without option to close them. I pressed home button and to my surprised, Touch ID purchased $9.99. I believe this kind of trickery and deceit to be unethical. I need to get a refund from apple and I would like this app to be taken down. How do I go about this? And I am kind of disappointed from apple that this kind of behavior is not moderated.
