I was held hostage in the car because I wouldn't pay the sudden increase to the rate we agreed upon. The app said I'd pay 155 (trip that normally costs 80). I agreed to x2 rate as I was in a hurry. At my destination they changed the price without notice to 217. I was locked in the car againt my wishes. I wanted to pay the agreed-upon 155, but driver refused to open the doors, which had no handles. I ended up paying full amount as I was in a rush. I should've involved the police in this theft.
