Uber India — overcharge in the veil of cancellation fee

Today at around 1:42pm, i booked a cab through uber in the pool category from aiims metro station. One driver named devendra picked me up. He got another booking from safdarjung enclave. The driver declined the rider's call. The other rider then cancelled his trip. Now even after his pick up request being cancelled, devendra goes to the other location and then came back at my location and dropped me and with my collegue at the same place he picked us from. He then asks me to book another cab as he is new in the profession and is not able to understand the uber app. I booked another uber pool but when i reach my destination, i was overcharged under the veil of cancellation fee for no fault of mine. Now uber says that i was late for my pick up whereas the driver picked me up, cancelled his other ride and then dropped me back at the location where i was picked up from. I followed up with uber and explained them the trouble caused but an automated answer was given stating that it was me who did not reach on time and that is why i was over charged.
