This is also a reason to subscribe with paypal. (Interestingly Disney+ felt it needed to send me an email every day for 3 months saying "your subscription is about to be cancelled!" after I did this. But when you go into the D+ interface, the ONLY thing you can do is update your payment information. So I did what anyone would do: marked their email as spam and got on with my life. But I can't help but wonder how many fake subscriptions D+ is floating like this...)
