Smule — unauthorized charges
I have contacted both Smule and Itunes without any luck. Basically Smule was charging us for subscriptions we never ordered. We would download a free version of an app and they would start charging us for a subscription. The subscription never showed up on our itunes account under subscriptions so we were unaware that they were doing it for months. They charge $377.36 before we noticed. Itunes refused to credit us anything older than a month.
