I had good experience with almost 50% of the drivers but some can be very dishonest. I Had to use Uber a lot during the month of May/June 2017 due to and accident that prevented me from driving.
Case #1: The driver charged me 100% more of the initial fare. He reported we were more than 4 riders. Not true. We were just my husband and I. After many claims from my part Uber eventually refunded me.
Case #2: The driver reported that we changed the destination address. Not true. He charged 100% more of the initial fare. Uber never refunded me.
Case #3: The driver charged me 100% more of the initial fare. She reported that I didn't provide the correct destination address. I explained to her that it must have been a system glitch. I was late for the appointment with my doctor because of that. She reported me to Uber as if I made racial discrimination remarks. NOT TRUE. I contacted Uber and demanded a meeting with the driver to clarify that offensive report. Uber never was able to sustain the driver's claim and eventually they opted to ignore my messages. Very disappointing experience.
I might use Uber in the future but I'll be very cautious checking the charges before I leave the car after the service. And I would advice to customers to do the same.
