MakeMyTrip India — Regarding invoice and customer care

I’m trying to contact make my trip customer care for the invoice of my journey booked on their app. The kind of service makemy trip is giving is very worst & when you will try to call their toll free number you will never be able to reach them to solve your problem. I booked my ticket through makemytrip booling id is NF[protected]. I have not received invoice bill of ticket fare. As I am trying to contact their customer care, I’m not able to reach them. I am still struggling for my bill as I have to claim that bill but due to their poor customer response I may lose 53000/- Rs.
