Uber India — I was charged wrongly

Address:

560037

I had travelled on uber pool (Bangalore from Vibhutipura to Vasanth nagar) where it showed a fare of Rs. 226.85. But as i had my UBER credits with me so i should not pay a single rupee to the driver.After completing my ride i got massage as '' your fare was zero'' on the Uber app. But The driver charged Rs. 386 showing in his mobile that fare. . Details:
date : 21.03.2016
time : 9.29 am
driver Devaraj.

So i need the Refund of my money which i paid to the driver that is Rs386.

I already sent 3 Emails to the "[protected]@uber.com".But still I did not see any response/Reply from the Support team o[censored]ber.
