PROBLEM! – Followgrow - Get More Followers for Twitter Review

This app hasn't charged my card yet and I am getting declined from Apple and can't download any other apps even thought they're free. I have money in my account but still, it hasn't charged me and it's been days! I wish I could get some help with this but no one answers. I really liked the app but it's just causing trouble.
