can i report my coworker or complain about this?

started a heavy sales focused retail job a few months prior. majority of customers that come in are only spanish speakers. i’ve lived in this area for a while and my boyfriend and family whom i live with are primarily spanish speakers so my spanish has improved over the past 3 years to a level in which i am near fluency. i am one of the only non-latina speakers at work that speaks spanish but sometimes people say i pass as colombian when i speak spanish so i guess that means i’m pretty good so far lol. besides that, there’s a coworker in particular who i haven’t had any specific problems with but he has chosen to specifically ignore me every single shift we have together. he never says hi to me and never talks to me. he will often speak in conversations with other coworkers in spanish thinking i don’t understand when i can—i think he’s trying to make me feel not included but i’ve just chosen to ignore him as well if he isn’t going to be friendly towards me. i will often just pass by to grab something and he will be speaking english and switch to spanish. however, over these past few weeks, there has been an ongoing problem of me in the middle of helping guests in spanish completely fine on my own, and he will barge in on the conversation and continue it from there. this frustrates me because not only is he insulting my intelligence but also taking away a sole sale from me which i get commission and incentives from. i’m not sure if he dislikes me because i speak a different dialect than him from a country that the people from his country are not particularly fond of each other, but i doubt that’s why. can i report him for this? it’s mostly speculation but now that he’s interrupting my conversations with customers it’s getting annoying.
