How do I cancel an accidental Apple News subscription and get a refund?

The process of signing up for Apple News is very quick and one can easily sign up by mistake if one hits a wrong key. Once one hit the subscription key there is no follow up by Apple confirming o declining one's wishishes to subscribe. It is so easy to sign in that I have mistakenly done it several times .A customer then gets charged one month subscription regardless if one cancels inmediately. It is my opinion that Apple should have a system to confirm if a customer actually wants to sign up to Apple News.
