UBEREATS NON DELIVERY

We ordered from Steers in Strand on the UberEats App. Received the message that our food on the way. We waited and nothing. No knock on the door, our door bell didn't ring no phone call. When I finally found a way of contacting Uber Eats (Very difficult to speak to anybody you can only contact online with difficulty) I was told the Driver was at our address and apparently waited 15 min??? My Husband went outside and didn't see anyone. We were sent a photo of a packet of food it could have been for anyone, no reference and a screenshot of a map of our road where the Driver was, that was most definitely not at our address. We were told no refund as the Driver was there. MOST DEFINITELY NOT OUR HOUSE! Why could driver not be sent back, what happens to the food I paid for R390 worth. I can't afford to keep feeding the Uber Drivers as this is the second time this has happened.
