They did this to us as well. And not only this, but they blocked our ability to push new releases until we opted into the new plan. And this literally happened on the day of a major release for our biggest client. It felt like we were being held at gunpoint.

We called them and begged them to give us an extension so we could perform the release, and their sales rep treated us like we were the irresponsible ones for not reading the emails they had sent us carefully enough.

We've since moved to Vercel and will never use Netlify again because of the way they managed this.
