I bought a $50 gift card through the app and a $50 card at Target. The $100 is posted in my credit but every single time I try to book a ride using the credits, the payment is denied. I have been given the same six "fix" steps over and over again, yet it still won't work. Uber has effectively stolen my money since it claims it won't give a refund. Now I have to sue them. I've filed a report with my state's attorney general and am exploring other governmental offices to help. #UberSteals
