This can literally kill the company outright.
We are a GSUITE company, and these stories give me nightmares. If one of my employees violated the ToS, even repeatedly, I expect to be told "Get off our system. We're giving you x days to move elsewhere, and have restricted <functions> until such time".
An immediate and total shutdown with literally NO response from Support is so drastic that it would trigger a lawsuit if it were any other company.
The only reason it doesn't in these cases is because it's David vs Goliath, and the victim company is already too dead and broke to sue.
Hopefully some lawyers will file a class action against Google - I have a Google My Business account that was suspended without cause (no abuse) with zero response from support.
