MakeMyTrip India — There is no option to update an email id or delete my account

Make my trip application doesn’t have an option to update email address or delete the account. I connected with their customer care at Facebook they are saying that they don’t have an option to update email. This is so irritating because I have changed my personal email address and I want to link my MakeMyTrip account with this new email address. They also doesn't have a proper customer care. I had to wait for their representatives to reply on Facebook. Its a worst service by make my trip.
