I enjoy the books but my issue is having a recurring charge of 10.69 and being told I've subscribed to this app at which when I go to the setting on the app and then to manage my subscription on google play i click that and google play pops up and theres no subscription on my google play for this app.as I was charge this within a couple days knowing I hadn't used the app makes me wonder how much of my money has been taken without me knowing off my card. How to cancel when its dont show here?
