MakeMyTrip India — Refund issue not yet returned

I booked a holiday package through MakeMyTrip. But later I cancelled it. They told me via mail that remaining amount INR 45000/- after cancellation charge will credited to your account within 7 - 12 business days. But till now amount is not refund. Even cancellation charges deducted from the amount thats what to be refund amount showing. But when that to be will happen only God knows. No satisfactory answer from them when I am approaching them. So many tickets/complaints registered regarding the same. MakeMyTrip is simply looting customers.
I will request take some strict action against MakeMyTrip as it seems looting customers is in MakeMyTrip's DNA now.
