You should probably put a one-click "I don't want to be charged anymore" button in any communications to the customer, to make sure you're not pushing them into a payment loop they don't want.
Because let's face it, half of your
'subscription-based companies' are banking on customer forgetfulness and high-effort cancellation flows to drive retention.
These are major factors that you _shouldn't_ attempt to 'solve' by successfully charging the customer for services they don't use or want.
If you do that, your whole business model will just be riding the underbelly of dark design patterns.
