How do I tell my boss I quit and not working out my two weeks notice?

I've been accepted for a new job and start in two weeks.

I've been treated badly here by my boss and a few others in my "team"and I want to quit.

How do I say this nicely without getting them angry?

I also don't want to take part in the Exit Interview.

As mentioned I was treated badly by my boss and the HR boss who does the Exit Interview.

I have nothing nice to say, so for me it would be a waste of time.
