Uber Package driver *****s my package, Uber powerless to help

On average I've been happy with Uber (only reason for 2 star review and not 1 star which this incident deserves) but have just learned just how easy it is for drivers to get away with *****ing things. I ordered an Uber package delivery for a computer part, biker said his bike broke down and I couldn't get hold of him through the Uber app after that, took it up with Uber and they said the driver insisted "there was nothing found in the vehicle". After some back and forth messages they said I'd have to subpoena Uber in USA for the driver's details to take it up with local law enforcement (not worthwhile for a R900 part). The driver gets away with theft scott free, which is disgusting of Uber to allow in South Africa.
