Srinath unfortunately you are not the only one who’s been through an experience like the above mentioned one,my story is almost the same,i had booked a return ticket Bangalore-Delhi on 3rd July and so far i have not received the return ticket in correct format and also the billing details.
            
        All i received was an email from one of the Reps in the service dept.with the itenary pasted in it which does not gives a complete info on the travel.I called the helpline on 4th July and i was promised that it will be sent right away with all their apologies,its been 6 days and i am still waiting for the billing details and also the return ticket in the correct format,Looks like they are waiting for an auspicious moment to send it .

This will be last time i visit Makemytrip for any kinda booking or flight info.
