Subway complaint: Very rude, disrespect employee and so called manager

I placed an online order with the app. I arrived at the pickup time stated on the app. I went in and waited about 5 minutes and one of the employees asked me what I wanted. I said I was there to pick up an online order. She looked at another employee and rolled her eyes. She asked my name then went to register to pull up the order. She rolled off a name, not mine and started making the order. I asked her what she was making and I told her that was not my order. She said well we don’t have your order . You must have ordered at the wrong store. I said no, I had ordered from that store would you please look again. She said we don’t have your order. I turned around to go out to my car fir my phone. They thought I was leaving and heard them yelling condescending comments as I went out the door. I returned with my phone to show the the order and she said that that was my problem, that they didn’t have my order, even though they never looked to see. She said that she was the manager, and I could take my additude and get out of her store. My only additude was to get my phone to show her the order, and ask her to recheck. I told her I didn’t have an additude until she got one. I also told her that my card had been charged and I wanted that money refunded. She said I would have to take that up with the app.
