A lot of charities in the Netherlands do the same thing, where you can't just give a one-time donation, but have to subscribe to a monthly contribution.

That is horrible enough as it is.

But then to unsubscribe, you have to call them (during their and your office hours) and endure another couple of pitches to keep you subscribed until you are finally allowed to cancel.

And then some of them even have a cancellation term of one month.
