Uber India — poor service from uber

Address:

Defence Colony 2nd Cross Street, Chennai, Tamil Nadu, 600032

Yesterday i booked a ride at the chennai airport. A car was allotted no
Tn 56 8829, driver xavier jerome. I kept getting message indicating that the car will arriver in 3 minutes. After 15 minutes i called the driver. He asked for the destination and mentioned that he would come.
But after 15 minutes he never showed up.in the mean time i kept getting messages that he would arrive in 3 minutes.
Since he did not show up even after 15 minutes he did not show up.
I called the driver twice and he cut my calls.
I cancelled the trip and rebooked and got a cab after 15 minutes.
You have charged cancellation of rs.30 for no fault of mine.
This is extremely poor service to say the least
You need to let me know as to what happened and return the charge.
