Question: What to call "Cancel" when "Cancel" is already the default action?
Answer: Rewording

I would try my very, very best to avoid using the term 'cancel' for terminating the subscription. Cancel is generally considered to be a safe action. Here, you are using it in a more destructive sense, thus causing the confusion you noticed.

If you manage to avoid the term 'cancel' for the actual activity, you can resume to use it for the cancel action on the dialog. In the mockup below, I used "Unsubscribe", but you can also consider other ways to express this like "terminate", "end", "remove" or "stop" subscription.

Not confirming at all

Alternatively, you could consider getting rid of the confirmation message completely. Instead, you could display something like this:

You could then also send the users a message by email saying essentially the same thing, and also allowing them to change their mind for a limited time.
