MakeMyTrip India — deducted refundable amount is very high

Address:

Chennai, Tamil Nadu, 6000037

I was booked ticket through mmt. (Makemytrip). Later i cancelled my ticket.
I spoke to customer executive person, he explained total deduction is rs.2000 for airline + 648 for mmt. Today i got refundable amount with deducted amount of rs.4448 which is more than 100%. Again i spoke to customer executive. She told rs.1200 for mmp (For deduction). What is the use of this portal. If i booked directly through airline portal, i could detected only 2000. But my bad luck i used mmt to book ticket. This is very very very very very very very very very very worst service.

Im very very upset for this # portal.
