Uber India — Driver's responsibility and total lack in service mind

Today we booked at 8.30 for a 'trip from Ganapanthy to KNG Pudur. Driver came promptly and picked up us. But after a short drive above 100 meters, he stopped and said he could not take us to destination due to trafic and abruptly dropped us. More than that he demanded Rs.20 but I refused. For your lack of service you have to compensate me. I[censored] charge anything in my next ride by adding any amount for this unaccomplished trip. I would not pay. Please note. Be satisfied that I do not penalice you for lack of service/
