Uber surcharges

Guys I'm not sure if you know and are aware. Uber is robbing us blind and we don't even know it. So you book a ride and driver accepts the price. Uber then puts a hold on your payment until ride is complete. Here's the catch, if the ride takes longer then they estimate you the rider is held liable for that trip. So say for instance there are roadworks or an accident, Uber actually puts the blame on you, and charges you for the inconvenience. This is completely ********* and should be reported to the authorities or Consumer Complaints at provincial government.
