A while ago my Uber account got banned when I had to leave for a flight at the SJC airport. I wasn't able to contact customer support or even get in touch with someone till almost 3 days later, after various tweets. Really disappointed in how they treat their customers. They also asked me to send pictures of my Drivers License and Debt Card over email to unfreeze my account for no reason. Luckily, I caught a Lyft. Uber needs to work on this.
