Uber driver con

The Uber driver was supposed to deliver a package to me, I did not say what it was and I paid R450 for it to be delivered, he tells me that I need to pay him R100 more to get my phone, I was shocked that he knew it was a phone. I said no and then he tells me that he is gonna sell it. I went to the police station and they say they can't help me. I reported this to Uber and they taking their own time to help me. This guy's name is Norman ********** 620, I don't have a reg number because someone else order the Uber. Please help what do I do.
