You have to threaten their customer support with legal complaints to make them comply with it, it's super frustrating to deal with. They do fold immediately when you do this though, so they know it's illegal but hope the frustration of getting through customer support will deter people (and avoids the legal problems).
And yes I know you can just switch subscriptions and use the early cancellation period there to avoid the hit back fee from cancelling. It's the principle that's scummy.
