Read the Dilbert Principle. If you are in too much of a hurry here is the Wikipedia summary of it. https://en.wikipedia.org/wiki/Dilbert_principle https://en.wikipedia.org/wiki/Dilbert_principle The situation seems completely unfair but you need to move on, life has some sucky points sometimes and a magic fairy isn't going to come down and fix things and set them right. I suspect talking with the management will only make things much much worse. You look much better to an hiring company if you currently have a job. Put your resume out and when a good offer comes in jump. Do not let the fact that you did great work and an idiot got promoted suck the life out of you.
