Work place harassment is serious... do you also have video/voice recording.. if not, I would suggest doing some.... but a cheap voice recorder.. I know smartphones have this.. but unless you have a flash memory, it can take up quite a bit if your recording through most of the work day.. haha
If you have told your supervisor or even higher up and they do nothing, you can go after the company also..
