Savaari Car Rentals — hidden charges with no invoice

Address:

8-5-370/401, Indra Residency, Vysya Bank Colony, Old Bowenpally, Secunderabad, Hyderabad, Andhra Pradesh, 500011

I booked an airport transfer service from savaari.com. But after boarding the cab at rgi airport hyderabad the company person called me and demanded to pay rs.250/- additional charges for parking and argued that they will not mention this in their final invoice. I have used his service on sep 01 2019 from pickup from bowenpally and drop at rgia hyderabad and they didn't charrged any thing but today sep 16 2019 they are demanding additional money inspite of charging rs.1721/- for drop to bowenpally which is higher than any one in market.
