Ola Cabs — Rough behaviour by cab driver

Address:

Kolkata, West Bengal, 700039

I hired a ola share (Devender Prasad ([protected]), White Swift Dzire WB07J0903. Share OSN[protected] for my old parents on 14th of August. I booked it from picnic garden to nagerbazar. I booked seats for 2 and both avail the journey. Tge driver told from uttar panchannagram bus stand there have another booking n in that booking they have 3persons so my parents try to adjusted with them. My qustion how can be it possible? As I know old share is book for maximum 2 person. So how can the driver took 5 passengers in a cab?? And all 5 are adult.
The problem is not end here while the car reach near nagerbazar the driver try to insisted my parents for drop out though the destination is not reached. And after while when they reach the destination the driver asking them for some extra money. My parents already paid the billing amount when they took the cab.
I never experienced this type of thing in ola. I regularly use ola cabs. I really feel good with the cab so I reffer my old parents bout that. But there experience is really bad. Please take care bout that.
