Economist cancellation still predatory

When I went to cancel my Economist subscription this morning the cancel button was conveniently unavailable on the app or any of the three browsers I tried so I had to use the chat.

Despite me saying, "stop showing me new offers, I just want to cancel" I was shown new prices with a 2-3 minute delay more than 5 times. Only when I told the "person" I would be posting this this on social media did they finally agree to end my subscription.

How is this still legal?

I do not recommend subscribing to the Economist unless you want to waste 20 minutes of your time fighting a bot to cancel.
