UberEats charged me R812.40 and never delivered my food.

I am so fed up with Uber Eats...I dont think I am going to continue using the app anymore. On Monday 24th August 2020 I ordered 6 pizzas from Mehanos on UberEats. The charge immediately went off from my bank account for R812.40 but then soon after the order jus dissapeared from the app. I never received any food. I called Mehanos and they said that they never received any order via UBerEats. I then contacted UberEats the very next day because I thought maybe the money's will be reversed by the next morning. They got back to me the evening by saying that I should contact my bank as it's not their fault. What the hell? I used UberEats app and was charged by UberEats for food I never recieved. It is the 25th August today and still have I recieved no money back or an apology from UberEats. This is frustrating and honestly terrible service. I have been using the app for a long time and have always had either food missing, late or cold. Most times when the items r missing I just tend to leave it because it's a whole process with UBerEats. The fact remains is that I was charged by UberEats and not by my bank. Why in Gods name is it anybody else's fault besides UberEats? Not even an apology was received until today.
