MakeMyTrip India — Refund of cancel train ticket under 3x Refund

Address: Village Lagda, Purulia, WB

I have booked a train ticket from Bokaro Steel city to New Jalpaiguri station with PNR no [protected] in train No. & Name: 15661-RNC KYQ EXP under trip guarantee program with firm assurance of 3x refund. I have paid additional INR 1460 for 4 persons as trip guarantee charge. But unfortunately, the ticket was not confirmed neither partially of fully. So, as per the firmed commitment from makemytrip I suppose to get 3x refund against my total fare. But makemytrip had refunded me only 1x refund that is the exact fare. Remaining 2x amount they have given a travel voucher with many conditions and limitation in booking. As there was firmed commitment from make my trip, I want complete 3x refund to my card through which I had made the payment for booking.
