There should be a law stating that you need a minimum number of hours using a subscription before you can be billed for it. At a minimum they should tell you how many hours you're using it each month.

I would genuinely sub to 3 streaming services, xbox live and a gym if I knew I wouldn't get billed unless I used it.

Unless it's a genuine commitment (e.g. my baseball team) there should be zero cost for zero use.
