Uber India — trip was started even before my pick up today

Address:

Bangalore, Karnataka, 560062

Dinesh Kumar Raju B - KA03AC6050 Tata Indica

Pick up was from Konanakunte PNB layout and drop to Accenture Bellandur.
Even before I could get my pick up I saw trip was already started this was at 7.40am. I immediately called the driver to check his location and he told it will take 15 mints. Whereas he was just 4 mints away when I screamed he told he will come to pick me up. I told him to cancel the start trip as he is supposed to pick me up first. Waited for 15mints he didn't turn up neither did he cancel. This is not a joke everytime due to drivers mistake why should I be charged. 100 of times they cancel seeing the drop location and we get charged. This is most ridiculous way of dealing with customers. I want a serious action to be taken. Why the drivers are not trained about the simple steps to be followed once the booking comes to them. Why customers have to face these challenges. I'm writing this complaint and my ride is still on and not been cancelled. Highly unacceptable and disgraceful act.
