UberEats Charing for cancelled orders 😡

I’m not happy with the level of service I received from Ubereats and the merchant Premium Fish and Chips Deport. I made a mistake on my order and couldn’t change it so I immediately went on Ubers app to try change my order. I was advised by Uber that I needed to contact the merchant. I called Premium Fish and chips Deport and the lady that works there knows nothing she placed me on hold and took other orders while I was on hold. Eventually she got someone on the line who said they can’t change my order. I told her I’d like to cancel my order which she did but I was still charged for the order and delivery by UberEats. I want my money back. All the links on Uber to explain how o claim my money back for this cancelled order. UberEats needs to allow people to change their orders on time.
