Money grabbing

When I tried to get an Uber 2 times in a row, I couldnt get any as it showed me a "failed attempt" msg. It didnt stop there, the Uber then for some reason automatically got me another Uber car (I didnt request it this time) after I got on a cab. And proceed to charge me a S$6 fee for cancelling.
