I came here looking for the same answer because I've run into the same issue with webinars that have a fee and the user expecting that a cancellation will automatically cause a refund to happen and when it doesn't file a dispute with their credit card company causing us to be charged dispute fees. It seems shocking that this has been an issue for over 5 years and has yet to be handled by GoToWebinar. I understand the need for an unsubscribe option for privacy as AshC mentioned but if that's the reason, then provide an unsubscribe option. In fact, I don't even see how someone Canceling even creates an Unsubscribe request; the unsubscribe request is a separate link called "Stop GoToWebinar emails." At the very least, if someone opts for the cancellation, the Cancellation procedure should inform the user that Cancellation will not create a refund and if they want a refund they should contact the organizer for their options prior to cancelling. It seems like at least that is something that could be updated very quickly.
