Protesting decisions

How do you protest the results of a fight? I've recently done a mma bout that ended when I managed a reversal. The position was single leg X guard and my opponent was crying and running away. Technically, I won if they go by the involuntary screaming rule as a verbal tap out. It's still amateur, but I don't like my ego getting played with here. The ref didn't stop when I was struck really good between my left eye and nose, but did after I was getting another advantage. My hand was not raised if you didn't figure it out. Is there someone with ABC, my local state, or the promotion itself? *Also, this is the second time that my opponent was not the set "guy." I crossed paths with him before weigh-ins. He was pretty meek and shorter than listed with bad posture on top of that. The guy I fought was noticeably taller than me and a bit bigger in size. He even bored the crowd by trying to lay on me. Any takes? I haven't seen any video of his "finish."
