Fraud
Your app is a fraud. When you first download it, it works fine but after you exit out it stops working and will charge you $49. There’s no way for you to dispute it since it doesn’t show up anywhere in your apple subscriptions.
Response from developer
Did you purchase the subscription through our website? If so, it won’t appear in your Apple subscriptions, since it wasn’t purchased through Apple. There is a dedicated option for this case in the app settings. Please contact info@pgcaseclub.com and we’ll help you process the refund.
