Uber India — Overcharging during uber pooling

Address:

Kolkata, West Bengal, 700094

My login mobile number [protected], email id [protected]@gmail.com.
I rode a uber pool on 3/3/17 in kolkata. The ride estimate was ~ rs 80/- during booking. There was no other riders (Which obviously was not known to me) for the same ride. When i deboarded the bill was rs 242/-, even more than a normal cab booking.
I find no justification of why i was overcharged like this and would seek for a compensation from uber. The details are attached.
