Bad service uber eats driver

I made an order through the app uber eats, the order was from Nandos. I paid using a debit card. My order wasn't delivered, I work around the mall. Your delivery guy told me he was at the parking I tried to understand which packing since the mall has so many parking. The delivery guy by the name Kenneth wasn't specific. Until after 30mins he sent me a picture of my meal in the dustbin. I felt that was too rude for something I have paid for to be put in the dustbin. What I want is my refund from uber eats. I called Nandos and they said they have nothing to do with the order, but I must contact uber eats.
