What's Wrong?

I have got charged 200$ without my consent. Refund is automated by bot, no human assistance.
It's unacceptable for a company to handle user experience like their own cash slaves.

I have never asked for a Max Plan, only Pro.

What Should Happen?

It should have stayed on the Pro plan, and bill me only 22$ a month, not 200$
