That sounds like an issue between you and the merchant (Stripe's customer), not Stripe. The quickest path to resolution, if the merchant is unresponsive, is to ask your credit card issuer to block payment to that merchant.

It's tough for Stripe to intervene here because Stripe is not aware of what contracts exist between you and the merchant, or how the merchant is integrated with Stripe. A scammer could initiate service, tell Stripe to remove the card, and still get access to the service (because the merchant isn't listening to web hooks). This is a new fraud vector that ultimately violates the trust between Stripe and the merchant.
