They did not give me the promotion despite me making my boss irrelevant

So I was a top performer in my team, and the most tenured after my boss. My boss still wouldn't praise me enough or give visibility of my work to his seniors. Guess he was always insecure that I would shine brighter.

So I decided to take my boss out by putting him under significant stress by making his role irrelevant. By simply DOING HIS WORK

I started doing his work and and making decisions he is supposed to be making. Specially during a week when he was gone - I pretty much acted as a pseudo boss for the entire team.

The final nail in the coffin was I somehow setup a meeting with my boss' boss and told him exactly how poorly managed our team was and how insecure my boss would behave.

6 months later my boss looked outside for a role and exited the company

And this performance review cycle I still did not get the promotion. They're saying they'll bring another manager above us but they haven't promoted me.
