[Resolved]  Make My Trip — udf not being refunded for delhi bound flights

I had booked flights through mmt for ahmedabad to delhi and delhi to kathmandu and back (Total of 4 flights that originated/landed in delhi). Upon enquiring about the udf refund the customer care officials have told me that they shall not refund the udf fees for me and my friends who had the same fights. The stated reason was that this refund is given only to those whose final destination is delhi.
My understanding is that udf is charged regardless of whether my final destination is delhi or not. Hence, i should be refunded the charge for all 4 flights.

Following are the details of the booking:
