Zero customer service

Left an item in the last river's car. Realized it 30 secs after he left. Tried all help options available on Uber app. No way to get in touch with anyone. Computer driven system. Tried to get in touch with driver via app but the help line is a pre recording of a lady repeating "hello hello" for 20 minutes then the call drops. Lost all my cards as well as my drivers license. No way to get help from a computer without being able to speak to an actual person. Too much risk for me as user. Will be moving my 10-12 monthly trips to a new service provider.
