Address:

103, F-Block,, Amity University Mumbai, Bhatan, Raigad, Mumbai City, Maharashtra, 410206

My wife Traveled from Mumbai T2 to Amity University, Mumbai on 12.07.2019 the fare was fixed as INR 1, 400/- But after arrival at the destination the driver asked for RS. 500/- extra, since she was alone could not argue much, and paid extra amount as well. I traveled the same route on 01.09.2019 by Meri Taxi, and paid only Rs. 1, 400/- .
Request you to look into this matter and I return the amount RS. 500/-
I have attached the booking details as well.
