I agree - if you’re sure you want to escalate - contacting the stack employees is an avenue to review any action here. Whether it’s moderators like you (you can access moderation tools due to reputation), elected moderators - going outside the community is always available.
I will link to this overall question on how to question moderator abuse:
The part that might be relevant here is trying to work it out here or with the local moderation team.
It's often best for you to try to work things out at as low a level as possible. If you have a problem with one moderator, it's faster for you to reach any of the other elected "Diamond Moderators" on your site as they have the most experience with your specific site and may even have seen other actions you have taken that give context to the issue at hand. Sometimes you want to go above someone's head (or even straight to the top) with a complaint or request, but realize that the recipient will wonder why this person with a complaint couldn't resolve it with the team of moderators that were put in place to do just that.
