What is going on with uber ? Someone left something in the car called me returned it now can't find returned item? Because it's not in the app anymore? Why now you have to go on line to report it 😒
Why are you wasting time on this?
It doesn't make Uber any money - they don't care.
It doesn't make you any money - and it elevates your risk.
It is not your responsibility to take care of other people's shit.
When I found something in my car that didn't belong to me, I dropped it in a mailbox. The nearest one. RFN.
If asked I don't have it, never saw it ... what is it?
