Subway review: Sexually harassed by employee and overcharged

I went to purchase a footlong Friday morning. December 13, 2019. One of your employees was just plain out disrespectful and rude. Also making sexual advancements toward me. I am also a male. Josh is what him nametag read. After repeatedly being told the advancements and jesters didn't stop. While paying for my sandwich I was over charged being told that I had ordered a deluxe. I tried to get a complete refund because of the whole ordeal. I handed him a 20 dollar bill and never received my change. I told him that I didn't receive my change and he said, " tough titty boytoy, the drawer is closed and there's nothing can do. I asked for management. The manager was him. Josh. I'm upset deeply and slightly disturbed. What can I do about this? No employee anywhere should be allowed to act this way. Anywhere. My name is Micheal b Bergeron and my cellphone number is [protected]. If possible, i would like to receive a follow up email about this . My email address is [protected]@gmail.com. thank you
