No, but there may be a contractual agreement between you and a provider where you have promised to pay for a service, and merely 'not paying' is not sufficient to cancel that. This makes far more sense in a non-digital world though, where you might pay for expensive services after the fact, rather than in advance.

In practice, most digital services will happily cancel themselves if you do just block upfront transactions. Many modern financial services/neobanks I've used have some kind of built-in functionality for this, even paypal has a page where you can manage & cancel all current subscriptions directly, blocking all future payments: https://www.paypal.com/myaccount/autopay/.

> Merely changing the card number wont work because bank updates vendors with the new card. I've asked but they they have to update vendors, i don't understand why though.

I believe it's because the 'card details' part is effectively a fiction for e-commerce. When you subscribe, the payment provider uses your card details to get a persistent token, which they can use to authorize future payments, and then they throw away the card details entirely. They just use the token alone to authorize future charges.

That token is somewhat independent of the specific card, by design, as unlike card details this means it can't really be stolen or leaked (it's only authorized for certain purchases from that one vendor) and it means all your normal ongoing payments don't break in the common case where you _do_ want payments to continue when your card is replaced.
