If someone steals my card, and uses it to pay for Netflix, how will I log in and cancel?

The simplest, safe route is to not give companies the newly updated number. If my Netflix lapses because I forgot to update the number after a card change (whatever the reason), they can email me, and then I will log in to my account and update the card on file.

You dispute the charge, just like any other unauthorized transaction. That's quite different than changing your card number under their feet, and will be received as such by Netflix.

Don't you cancel your card when it has been stolen?

Do companies that do subscriptions know when multiple accounts are using the same card number? Just curious if they try to use something like that for fraud detection or anything. Then again, I don't think they'd care. Just take the monies and let the card people deal with it.

During the whole clamping down on password sharing era, I'd be very surprised if some folks haven't had to pay for multiple Netflix subscriptions (for summer houses, or their kids off at college, that sort of thing...)
