I have been Sexually Harrased ..what do I do

I recently went into a car dealership in hopes of purchasing a new vehicle. The sales man came to give me assistance but at the same ti,e he was making sexual remarks and gestures. I overlooked him at that point but it has gotten to the point that every time i go into the dealership to get info on my application he says things out of character. I recorded him yesterday from my phone talkin about my but, what size underwear do I wear, he can get it, and he actually put his hands on my but and I told him not to touch me but he said he was just getting something out of my pocket. All i want is to know whats going on with the finance deal of the loan. This is a married man and i even told him he should be doing things like that and does he harrass people and he said yes people like me. I have to go back there today and I am so uncomfortable. All i want is a vehicle, What should I do
