Uber India — changed driver and vehicle without my knowledge after booking

Address:

141. 8th cross. 3rd main. RMV II stage.HIG (Dollars' colony), 560094

I booked a ride from my home to bus stand on 1.4.19 at 08.00. While i was talking to the driver on phone, he kept me on hold for over 5 minutes (Mr omsekar-driver) and then new driver and vehicle appeared on my screen one mr sunil, he too us to a different location and said that is the location i booked! And changed booking to bus station and charged me rs 140.00 instead of 89.00. He was arguing all the way that i should pay. I said i want to talk to uber centre. I called mr omsekar on the mob he called me. Guess what mr sunil answered! Is there something going on without uber's knowledge. My concern is there is a serious safety issue here. We could have been kidnaped, assaulted, raped or murdered. May i request the concerned personnel to take action asap sort this serious safety issue with uber.
