In Kolkata do you really have any rules and regulations? You don’t put the AC on at around 35degC. The drivers demand extra cash for turning on the AC. They call you and ask about your drop location, mode of payment and then cancel immediately. I have stayed in Multiple cities where you provide your services but I feel the worst is in Kolkata. Your fares are way higher in Kolkata than in MUmbai and Bangalore for the same distance.
