Uber India — Fake chargers

Address:

560043

I have taken a driver with Uber on 17/5/17 Horamavu Agara, Horamavu, Bengaluru, to Aswath Nagar, Marathahalli, Bengaluru, Karnataka 560037, India. The charge was around 183 and final i got bill of extra 100 rs for the cancellation of last two cabs. The cab was cancelled as per the driver request since he said it takes long time to cancel it and why I have charged for the cancellation ???
I have never such worst service there no customer service number also

Regards,
Aswathy
