Search for another job offer in a place you fancy, then talk to your manager about it.

Either you're valued and suddenly the procedures won't be an issue, or you have found yourself another place to work.

But take your time, no rush. Just make sure you keep showing your value in your current job, that's your only currency.

Right! It's amazing how many immovable processes suddenly become very flexible when the business is about to lose someone they value.

In this case though it would take a lot to make me stay. They have already lied or given a deeply misleading impression of your seniority. I would not expect their overall management style to change.
