Deducted money, no delivery received

I ordered food, money was deducted off my account and there's no details of my order on the app nor did I receive delivery of my food. I tried to call all your helpline numbers and that also leaves a lot to be desired as you don't get assistance. Eventually contacted the restaurant, they gave me the number for UberEats and I was refused any assistance as I was not a store. The restaurant I ordered from told me to rather order through Mr Delivery as they always have problems with UberEats. Disgusting customer service! UberEats, I now have to wait 24 hours for you to look into this mess you have created and I want my money transferred back into my account.
