Actually I booked a flight ticket from Madurai to Chennai and while processing the payment, it resulted in error, but they deducted the payment from my account of nearly 20K and delivered no tickets.
I called their customer care and informed the details but they didnt even answered me properly. They easily said that we have not received any such transaction and simply said that there is no such account registered on my name. I was shocked to hear this from MMT.
Then I called my bank and asked them for the transaction confirmation ID and passed that to MMT customer care. Then only they accepted their mistake and promised to refund the payment in 72 hours(3 days). But it is more than 10days, yet I havent received my payment back.
Such an irresponsible service, I even forwarded a complaint email to service@MakeMyTrip.com and contacted too many times via Twitter. But everything was resulted in failure.
I highly recommended never never use MMT for booking your tickets/hotels for emergency:(
