Ola Cabs / Ani Technologies — collecting extra amount from customer

Address:

Chennai, Tamil Nadu, 600019

While booking through ola app it has shown only 188/- once we completed the trip cab driver is asking me to give 386/- since the app is shown separate amount for fare increase¹ = ₹188.1
They are collecting separate amount as 'fare increase' 188/- a part from below mentioned base fare, distance fare, ride time fare, taxes. When i check with the support they are telling the reason as when demand is high at that time they are putting this extra amount and cheating the customer.

Base fare = ₹30
Distance fare for 13.5 km = ₹81
Ride time fare for 40 min = ₹60
Fare increase¹ = ₹188.1
Taxes = ₹27.28
Total bill (Rounded off) = ₹386
