Order not received, no refund received

I ordered a meal from Mcdonalds Observatory of R97 the driver kept passing my office, I tried calling him but received an automated message saying 'your call cannot be connected' I then messaged him on the app resent my address as well as advised him that there is a big sign on the building with the companies name. I called about 3 times with no success. The driver then completed the delivery but I haven't received my order, he attached a picture of my food left on a pavement which is not even nearby where I was located then I lodged a complaint on uber eats and they keep saying they cannot issue a refund as the driver followed all instructions and sent a picture to proof my order was delivered. I kept sending emails to dispute this and all they send back is 'we cannot issue a refund as the deiver tried getting in touch with you with no success' How can you leave someone's food on a pavement and claim it was delivered. Why would I go through all this trouble claiming I didn't receive my order. R97 is alot of money and I have been using uber eats for quite sometime. I am very disappointed and utterly appalled by their ****ty service!!!!
