Paid for food I didn't received and being refused refund

I have ordered food via UberEats today, Delivery Guy text me starting he is outside then i went out to collect my order that i paid online by the way. delivery guy was not there and when i text him he is telling me he is outside Monke Centre which i have no idea where that is because my Delivery Address is 107 Ambition House in Voortrekker. I have informed uberEats and was informed that i wont be refunded, question is how when their Driver when to the wrong address?
