Indian not paying me in usa

I used to work in 7-eleven like a month ago, while I was working he would withheld money for months and it was affecting me with rent and everything. I told him I was leaving the job and pay me back the money he owed, he stopped responding my texts. And when I went to the store we was like take this money and rest I will put in your bank account shortly.

I know working in cash, I should not have trusted him like that, I don’t know what I was thinking but I agreed. I moved from there to another place after I moved he didn’t respond my texts and when he did he just said I will call you tomorrow and never call.

I was frustrated and I wrote that he was “chutiya” and he was scared of me so he is not responding and all kind of things, I guess that got under his skin and he started writing he was not scared of me, and that I stole money from his store, stole lottery, and stuffs (which I did not do). And blocked my number. I don’t know what to do now.

I even threatened him of going to lawyer and filing a lawsuit from a new number, he is still not responding. I am in student visa here, so going with lawyer might backfire to me.
