Uber India — rider pass

Address:

Chennai, Tamil Nadu, 600116

Uber issues rider pass for 15% discount.
But when I try to book, the prices are shown higher than normal and then reduced.
When checked with friends account with same destination and at the same time, the fare shown with out rider pass is same as the amount shown in my account after discount.
After that I checked it several times in the past 2 days, every time the account with rider pass is shown higher charges and given discount.
Below attached pictures, check ubergo rate, normal account is 122rs and one with rider pass is 140rs and discounted to 119rs
