Any advice about a rude and mean ex at workplace?

Any advise how to deal with a mean aND rude ex? I ve gone as far as bringing it up to his supervisor but it s a small company and my company really needs him so he might not take it serious. Everytime we have to interact he's rude and mean to me. Makes work environment uncomfortable. Thank you in advance!
