EaseMyTrip.com — Wrong amount refunded after cancellation

Address:

WZ 51 khyala village

I booked ticket of airvistara from easemy trip booking id EMT93853562. Of economy flexi class, where airvistara charges no cancellation fee, and while booking easemytrip was also promising the same (zero cancellation fee) but after cancellation i got 3480rs deducted from 3670 rs. In the name of airline charges, but airline doesnt charge for economy flexi, and i am not the only one who faced this, this is done intentionally, i also booked same class ticket of airvistara from airvistara official site and they return all the money to me
