One time I bought a .dev domain, which is/was run by Google, and after missing the renewal deadline by less than 24 hours, the renewal price jumped from less than $30, to $800.
No idea, but it would cost me more to fight it than it's worth. And other people have reported similar issues but people refused to believe them, so I doubt I would get much sympathy.
