how to deal with heavy misgendering at work

I'm not going to lie, I am about ready to go on a extended break or even quit my job because of this. it really gets to me and affects my mood no matter how stoic I try to be about it and try not to let it get to me.

I am still very early into the medical process and social transition, I still kind of help my dysphoria by still having a little bit of presentation at work (foundation, leggings with shorts, earrings). most of my work colleges know and try really hard. with the exception of my boss who still heavily misgenders me but I at least do notice he is trying so that is what matters?

I guess my main issue is I work at a pretty heavy customer facing job and although my team are trying. I get pretty brutally misgendered and thrown all these masc slang terms by customers like "man, dude, bro, guy, sir, gentleman" I feel like some people see me and do it on purpose. when it really annoys me and my energy to cope gets low I correct people but I find the moment i do it, people will do it again out of spite!

I am not sure what to do. I am getting a new name badge soon with hopefully one with my correct pronouns, both with my correct name. both with a Acon symbol. I have also been tempted to go it presenting more with heaviler makeup
