This would be an even further step. Reminds me of how Cable /Xfinity won't let you cancel sports package over chat....they send you a link to your phone that you must click, log in (password verification, captcha etc...) and than change the terms of your account.

Even on phone they make you respond to a text to confirm. Of anything happens (internet is not working, whatever, your bill will not be reduced).

Every extra link you must click to a third party source will remove half of your people.

It's an egregious step, imo
