Things to consider

Performance clarity: were deliverables, priorities, support and review criteria agreed?
Communication: did you explain the problem, ask useful questions and set boundaries without personal accusations?
Procedural fairness: were concerns heard, records kept and escalation routes used when needed?
Respect and accountability: was the pronoun concern addressed, and was oversight sought when necessary?

Communication skill improves the chances of resolution, but it cannot guarantee a fair outcome when the person holding authority refuses to engage. Escalation can be a legitimate and sometimes necessary part of resolving the problem.
