I am a temp for a big company here locally. I have been harassed for close to 2 weeks by a male coworker who is also a temp. I have reported him 3x

My boss at the company told me Saturday that I was the 2nd person to complain about this guy in less than an hour and that he was going to be fired, she even stated this in a text which I still have. I have PTSD and now that the company knows this i am being treated very poorly and negligent of the situation. This coworker harassed me again last night at work. Nothing has been done about it still and I have had to leave work 3x early because its upset me so badly. My other boss at the temp agency informed me this morning that they are conducting an investigation. I feel helpless and discriminated against.
