Terrible wrong order experience and service!

I'm so dissapointed at the terrible service I received from u we eats 2 days ago. I placed an order to the mama putt restaurant and my order was delivered with the incorrect order. The driver gave me nothing but tounge and cheek and there was no number to call and complain about the incorrect order, I was just told by the driver that I should pay and someone will get back to me about my incorrect order but instead, when I immediately raised a complaint on the app and I uploaded a picture of my order versus what was delivered whilst the driver was still there with the order,I promptly got an email response telling me I could not be helped because I laid a complaint 48 hours after the delivery was done. Which was utter nonsense as once again I had done it immediately When the food was presented to me. I also proceeded to send another back to the email prompt stating that I complained seconds after my delivery and once again another 48 hour email was sent back to me. I am furious and would like this matter to be resolved as I paid the full amount for a wrong order trusting that Uber eats would resolve the matter but still nothing has come to pass.
