Uber package Not Delivered - WC

Package delivery was booked and collected by Uber driver on 15 April 2026 (Cape Town). Upon delivery, the person was unable to collect same from driver due to unforseen circumstances. Uber driver left with parcel. Contacted Uber driver who did not answer, contacted Uber (on their extremely unhelpful App), to request an investigation as to what hapened to the parcel, who in turn advised that the driver confirmed that the item was not found. How is this possible? If something is not delivered, surely it should either be returned to the sender or taken to a central point? None of the Uber numbers provided works and good luck trying to find a person or manner to escalate the matter. I need the contents of the parcel and insist that same is returned to sender. I can provide the drivers name and reg number to assist if Uber is interested in resolving this matter.
