Disciplinary action help

So at my store there is problematic customer that always complains and causes scenes when he doesn't get his way (including recording and harrasing associates). A few weeks ago I had an encounter with him talking nasty and I told him " no need to be a d*ck brother I'm trying to help you out" in a conversational way. He proceeded to yell in my face while smiling. As it seems like he was trying to set me up and the next day I got a DA orange that said "I failed to deescalate situation and used profanity against the customer". I contacted the market manager and nothing is changing. I understand a DA is fair but don't think the wording/color is fair since it leaves out a lot of details and context and paints a different picture of what really happened. They clearly took his side of the story and literally just wrote one sentence on what happened.

I don't know what else to do. Should I go with ethics to it? Would they be able to help?
