I hate it when online subscriptions make it hard to cancel. I have encountered 4 models - in order of preference:
1. Press a button, and have the subscription run out at the end of your paid period. No hassles, and you are getting the full service for which you paid.
2. Press a button and cancel immediately. Makes timing more important, and to be safe I usually cut a day or two off of my subscription.
3. Write an email to request cancellation. Sometimes they will cancel immediately, no questions asked. Due to uncertainty of CS times, usually cut several days off subscription.
4. The WORST is where you write an email requesting cancellation, and they write back trying to get you to stay (sometimes with offers, which may not be terrible!
)
I have one subscription right now which states 'cancel anytime' - but they don't say how!
