Ditto.

If you've ever lost access to Google, you'll never rely only on webmail again. There is absolutely no way to get in touch with a responsive human there. You may mysteriously get access back after a few weeks. Or maybe not. In the meantime, their online "help forms" will direct you to other forms, none of which provide any indication about what to do in cases when Google has erred.

There is literally no recourse.
