I lost an item

So on the 23 of December 2017, i took an uber to work like normaly.. but on that they i had my router n its battery was dying so i asked the driver to charge it for me. When we ended the trip i had forgoten my router with the driver his name is Smiso car reg is NUR38713 toyota corolla. Here is the most frastrating part i tried to call him no luck, send uber the email to get his details kept receiving autometed responses that never helped me out till this day even wrote on their page on facebook same thing no help... i tried again to phone the driver fortunately i got hold of him n he said his got it with him its safe that was on the 29 of December 2017 but he said something that we cant meet on that day as he got things to do and he will be off i must phone him on the 3rd of Jan 2018 n i did from then on he never picked up any of my calls n never responded to any of my massages hence i explained that i need those simcards to register etc no response, okay i then decided to take a day off to try sort this out and went to their offices in Durban North i was helped by a lady there forgot to take her name, explained to her wats going on, she also phoned the guy of which i failed to understand why caurse i told her he wont pick up, i then suggested why dont u call the owner of the car? Coz he would help us find the guy she told me they dont have DATA they cant search for the alternative number... these were her exact words “as soon as we go back online i will find the number for you” so it cant be that till now they dont have DATA and no one has contacted me ever since. I need help as i still need my router its under contract and still paying for it?... to get hold of this guy to explain himself and possibly get my router back ... I really dont get why this issue is taken lightly cause im incurring loses n this is just atter abuse which is not in accordance with CPA
