Recently signed up with Uber; first time tried to use was in Miami area; drivers never showed up ($35 cab ride back to hotel), emailed and complained to Uber, they sent email back telling me that they reset my phone number and now everything SHOULD work; tried again next evening, went out to dinner with friends, once again used Uber app and sure enough it sent me to another window asking if I would pay SURGE, first time said NO, then immediately sent to another page asking "ARE YOU SURE" said NO once again, then was informed car on way, waited outside of restaurant 15+ minutes and NO Uber, hailed taxicab ($40) back to hotel. Then next day found $55 cancellation charge on credit card... thank goodness Wells Fargo understood and removed charge, Wells Fargo agent said they have had several of these experiences
