Why Uber is losing so much money? The biggest part of the problem is that Uber is a relative small fish in the market and is not getting nearly enough customers. According to analyst reports, as of August 2015, Didi Kuaidi completed seven million rides as opposed to Uber's one million.
He also got a $20 ride credit, but only after he specifically asked for it. It isnât just riders who are frustrated by Uberâs lack of contact options. A member of the Consumerist staff once took a ride where the driverâs Uber app was on the fritz, causing her to lose multiple fares. The driver explained that even she didnât have a phone number to call the company, just an e-mail.
