Account suspended for "child sexualization" - I'm a special education teacher. How to reach a human at OpenAI?

A ChatGPT Plus user, a special education teacher and speech therapist, reported their account was suspended on September 8 for "sexualization of minors." They believe OpenAI's AI system incorrectly flagged professional education terminology as violations, and no human has reviewed the context. The user, a loyal customer for over 12 months, is seeking advice on how to contact a human at OpenAI to resolve this issue, as the false accusation harms their professional reputation.
