Dominos Pizza — Refusal of re doing my order

I ordered a large thin crust half olives and half chicken and mushrooms. I went to pick up my order and it was a large thin crust with full pepperoni. The Indian lady told me that is what I ordered. I told her that half olives and half chicken and mushrooms do not sound like pepperoni she got upset and started yelling and said do you want this. I said I don’t eat pepperoni make me what I requested of you. She said she’s just going to give me my money back. I’m very disappointed I called her and asked for her name and she told me she doesn’t have to give me her name. They should have made the pizza for me and not refuse my money
