I can tell you they are STILL stealing tips from drivers. It happened to me recently. They changed a $38 tip to $26 two days later. Then they took $5 of the lowered tip to pay the base fare in the statement. Leaving me with a $21 tip and myself paying my own base rate. I have proof and puctures backing up everything, and have contacted them a dozen times. All I get is scripted generic responses about how the customer can change the tip at any time and apparently as many times as they wish. Also, their proof is their own doctored statement with the altered tip amount. They absolutely are ignoring and refusing my MULTIPLE requests to speak with upper management and it ended up giving me a negative balance of $17 which they took from my next trips. So a billion dollar company thinks it's ok to steal $30 from good drivers that they would not exist without. Pathetic. By the way, that base pay was for STACKED Walmart orders with over 40 miles of driving. It's literally highway robbery. The ONLY reason I take these requests is because of the TIPS and promotion bonus and they turn around and steal it right back. Also I know the customer and they did not alter any tip amounts. Uber won't listen, so I hope their customers are seeing this and do something about it. Maybe it's time for another class action lawsuit because it seems the lesson was not learned.
