I believe you are incorrect: https://cloud.google.com/support/ states $250/month/user. Hence, it seems to be tied to a single contact person, why else would it state pricing per user?

Regarding suspension, if this is the case, why do we see so many desperate cries for help from people whom are unable to get in touch with anyone at all at Google to help them with their termination? They have to resort to public blog posts and hope that a good Samaritan at Google comes along, sees them and acts.

They all have the same story, "couldn't get in touch with anyone, "tried to appeal, denied without explanation" and they all had several days if not weeks of downtime.
