Uber beyond pathetic

I have complained about the bad attitude of Uber before, but now I am purely disgusted. The negligence of their drivers have cost me additional expenses in flights and other costs. After complaining to Uber their adamant response is that Uber drivers are independent and Uber does not accept responsibility for their actions. I find this difficult to comprehend, so who is responsible for the drivers and their actions if they are transporting riders under the Uber banner? Ubers response to complaints has been nothing but pathetic. They even went as far as blocking me from social media. Just highlights the integrity and ethics under which uber operates.
