ORDER NOT RECEIVED

So, on 25th Jan I ordered from Nandos Sea Point through the UberEats app. I clearly stated my address and even left instructions on my order. The driver kept sending messages that he'd arrived but I never saw him. I attempted calling him several times but his line wasn't going through. He claims to have called me, however I didn't receive a single call from him. I even gave him an alternative number thinking my network could be bad on the number registered. The guy went ahead and marked the order DELIVERED!!!! While I didn't receive anything!!! I went to Nandos to report the matter, they made it clear that they're not involved as the money paid goes to UBEREATS. At this point, I just want my money back!
