Angry Rider

took a trip on the 27th of july and lost my phone and cash. i tried to call the driver and he said he would return my things but now 15th of Oct the driver has been telling mt lies and keeps saying he will return my things but still noting. i have sent emails to uber and everytime they tell me the still investigating. Last week Wed the driver told me my things had been handed over to the uber office in Rosebank but i still have not got any feedback from the two parties.
