They took my money! I canceled my free trial shortly after signing up and a month later, I was still charged. I certainly unsubscribed after being dissatisfied with the app, and gave feedback as to why the app didn't work for me. To my surprise, I was reminded via email that my subscription will end on Feb 6. Still, my account was charged today Feb 5, one day before it claimed the subscription ends. This is a huge dissappintment. Amazon needs a better refund policy!
