I got an email from Uber Support saying: We are winding down the Enterprise Rent-A-Car program with Uber after a periodic review of our business strategy. We have enjoyed our partnership with Uber and Uber driver-partners, and we really appreciate your business. During this transition, we want to make sure we provide you with the best possible service. After returning the vehicle, you will be refunded your deposit less any outstanding balances. In addition, Uber has said it will have support representatives available. Grrrr.
