"Dormammu, I've come to bargain"

A rough go at translating:
Strange: "Dormammu, we have to talk!"
Strange: "Dormammu!! Dormammu!! It's Dr Strange!"
Dormammu: "It's the noisy neighbourhood nuisance."
Dormammu: "Stop it Strange!"
Strange: "Dormammu, we have to talk! [Something about a deal!]"
Dormammu: "Hey How'd you get in?"
Dormammu: "I don't want to see your face anymore!"
Dormammu: "Help! Police!"

I'm not the best at translating Japanese, but I saw the "Help! Police!" at the end and had to have a go. I'm guessing "Dormammu, we have to talk!" (Doomamuu, hanashi ga aru!) is the Japanese version of "Dormammu, I've come to bargain!" but can't find the scene on Youtube to be sure.

Edit: fixing "how'd you get in" line.

Further Edit after further thought: "Dormammu, we have to talk! [Something about a deal!]" could just be another way of saying, "Dormammu, I've come to bargain!"
