From reading the whole thing, it kind of seems clickbaity. Yes, they're the only user in the "organization" that got banned, but they apparently still are using the other "organization" without issue, so they as a human are not banned. There's certainly a valid complaint to be made about the lack of recourse or customer service response for the automated ban, but it almost seems like they intentionally were trying to be misleading by implying that since they were the only member of the organization, they were banned from using Claude.
