PhD Advisor is Inexperienced Junior Faculty, Possible Bully, Who do I Tell?
I believe properly answering your question depends on providing more specific detail, e.g. which is the country. Institutional structure and the corporate culture can be very different between, say, Mexico and China.

I believe you have a broken relationship with your current advisor. I will not attempt to judge a reason for why she did what you describe, or whether your account is precise and complete. 

This means you should primarily focus on getting away from this person while trying to find yourself another PhD advisor. Accomplishing this will do most of the "official communication" for you. The department will know there is a problem, and you both will be moving towards a healthier relationship.

So my answer to you is: the person you should talk to is whoever is responsible for shifting advisors in your institution. If you cannot change advisors for whatever reason, then it is the person responsible for smoothly terminating your contract locally so you can get better training elsewhere. The conflict itself becomes self-evident as you move to a better stand. 

Good luck!
