[Resolved]  EaseMyTrip.com — Extra charged for Reschedule

I booked the original ticket for 10th July Air India BOM DXB by paying 36, 342 for 3 Passengers. Now I went ahead and reschedule the flight for 7th Aug. While rescheduling on the EaseMyTrip website it asked me to pay a total of 13249 (Reschedule charge and convenience fee). I paid this, but the ticket went in pending and I got an email from EaseMyTrip asking me to pay 6856 extra for fare change through the link provided. I paid for that as well and got the ticket confirmed.
Now when I got the new ticket it mentions a total amount of 49, 591 INR. 49, 591 - 36, 342 (Original ticket fare) = 13, 249 (Reschedule convenience fee which I already paid on the site).
So where extra money of 6856 has gone, why this amount doesn't appear in this new ticket? I was fooled and they took this extra money in the name of fare change. But the truth is fare didn't changed.
