Charging money after un-sibscribing?!

So I downloaded this app and started the free trial version of the membership thing, and Once I realized how BAD of a website it is I un-subscribed and deleted the app, next thing I know I get charged 9.99$ + tax... Honestly, you dont even have the dubbed versions of 9 tenths of the anime you have and charge 10 dollars even after un-subscribing?!
