Ola Cabs / Ani Technologies — excessive billing

Address:

New Delhi, Delhi, 110075

Hi
I had a trip from sector 4, dwarka to indira gandhi international airport on 5th feb 2018.
The estimated amount was rupees 340 and i have been billed rupees 690, which is clearly disproportionate and disappointing.
The alternative route taken was longer and i was still stuck in traffic.
When i mailed to resolve the issue-your good for nothing-executives mailed that it cannot be resolved. I payed the bill and it was found that rs 150 has been added to my bill as parking. How will i know why he parked when he just dropped me? Why am i paying parking? It was a pick and drop service. Why will i pay the parking? He had already taken a longer route (Please check the image) and i reached on the nick of time.
This is completely non-sense and cheating.

I want a refund for the same.
