Work issues ive been having there is a lot more but this is just the baisc stuff?

At work there is this kid who using profanities towards me all the time, even when i tell him to stop he doesnt, he once threw a headse at me and called me profanities also Ive been telling my managers and theyve been claiming they have talked to him, this there anything else i can do? The way he acts is only directed towards me, and Ive asked him many times to please stop and he hasnt.
