UBER DRIVER STOLE MY PHONE AFTER IT FELL OUT IN HIS CAR WHEN I TOOK A RIDE FROM HIM

I had to take a Uber to my friend as my car was in to be fixed. My friend organised the driver, who was WHATMORE, CAA155750, I called my friend when in the Uber then I got there and wanted to see if I got calls on my phone, but the phone was not with me. I knew it fell out in the Uber. I tried to contact the Uber and so did my friend, logging several calls just for Uber to eventually get back and say it was not in his car. But i know it was in the back of that car as I would have heard the phone fall out and we checked, in her complex immediately. Uber closed the request without anything else. this is pathetic to know that you cannot even trust a freaking uber driver as he stole my phone and in my situation, this was the last thing i deserved, I had a car with expenses and now I have no money to buy a damn phone and i need it as i work from home. I would have given the uber driver some money for returning my phone, but he decided to be untruthfull and rather ***** from someone
